Genealogy goes through swings and trends in fashion.

At one time, it was the preserve of titled and landed families, families who appeared in Burke’s or Debrett’s peerage. But that was such a sad way of doing genealogy and of tracing family history. It was reduced to collecting the names and dates of lineal ancestors, often failed to look at contexts or touch the real people, and was oh so badly class laden.

Thankfully, the television series Roots in the mid-1970s created an interest in the genealogy of the oppressed, but also recognised the role of collective family memory in creating identity.

For the past 20 years or more, the television series Who Do You Think You Are? has shown us how the stories of ordinary working class families and families from diverse ethnic and cultural backgrounds have equally colourful and romantic stories to tell.

A new trend has emerged with the popularity and accessibility of cheap DNA tests, which is good for finding long-lost or discreetly hidden half-siblings and lost cousins, but very poor at telling us the real stories that went into creating that sample of spittle.

Genealogy and family trees are always dependent on collective imaginations and identities. In any family tree, some ancestors are counted in and some are counted out. All genealogists make choices that are based on the needs of a family or an individual to provide a colourful illustration of their sense of identity within community, with place and across generations and down through the centuries.

But a new aid that many genealogists are unwilling to give adequate attention to involves the use of mathematical projections.

I was perplexed by the title of Dr Adam Rutherford’s recent book, How to argue with a racist. Genealogy, when properly pursued, shows the inherent stupidity of every form of racism. And Dr Rutherford, in fact, is not arguing with racists – he is totally dismissive of racism, and points out the absurdity of all racist arguments.

One way he does this is through his critical examination of genealogy, its purposes and its methods, in Chapter 2, headed ‘Your ancestors are my ancestors’ (pp 67-107).

He points out that in the study of genetics, there is an assumed generational time of 24 to 30 years, and he points out that in every generation back through time the number of ancestors you have doubles.

What this means is that over a 500-year period, I have 1,048,576 ancestors. By 1,000 years ago, I have 1,099,511,627,776 ancestors – that is, over a trillion people, a number that is about 10 times the number of people that ever existed.

He says, ‘This apparent paradox reveals quite how incorrectly we think about our ancestry.’ Our family trees coalesce and collapse in on themselves as we go back in time. I certainly have a trillion positions on my family tree 1,000 years ago. But the further I go back, the more frequently these positions will be occupied by the same individual multiple times.

He points out that family trees coalesce with startling speed. ‘The last common ancestors of all people with longstanding European ancestries lived only 600 years ago – meaning that if we could draw a perfect family tree for all Europeans, at least one branch on each tree would pass through a single person who lived around 1400 CE. This person would appear on all our family trees, as would all of their ancestors.’

I have taken part in some of the programmes in the series Who Do You Think You Are?. Alan Rutherford recalls an episode in which the actor Danny Dyer found he was 22 generations in direct descent from King Edward III in the 14th century. But, as he points out, ‘the chances of anyone with long-standing British ancestry being similarly descended from Edward III is effectively 100 per cent. It is true for Danny Dyer, and it is true for the majority of British people too.’

It is true for everyone in this room, and it is true for everyone in this new book by Rod Smith that we are celebrating this afternoon.

But it goes so much wider than that. In conversation, a Muslim theologian asked me did I know that as humans we share 50 percent of the same DNA as bananas. Actually, there is some truth to that startling statistic, although it is not the whole truth.

This idea may have originated in a programme in the US run by the National Human Genome Research Institute in 2013 and led by a genetics expert, Dr Lawrence Brody, as part of an educational video from Smithsonian Museum of Natural History, The Animated Genome. That video noted that DNA between a human and a banana is ‘41 percent similar.’

The scientists working with Dr Brody compared the protein sequence from each banana gene to every human gene. Essentially, they took all of the banana genes and compared them one at a time to human genes. Their study shows that about 60 percent of our genes have a recognisable counterpart in the banana genome. ‘Of those 60 percent, the proteins encoded by them are roughly 40 percent identical when we compare the amino acid sequence of the human protein to its equivalent in the banana.’

It may seem shocking that so many genes are similar in two such vastly different things as a person and a banana. But actually, it’s not. ‘If you think about what we do for living and what a banana does there’s a lot of things we do the same way, like consuming oxygen. A lot of those genes are just fundamental to life,’ Dr Brody says.

As humans, we not only just share a high percentage of DNA with bananas – we also share 85 percent DNA with a mouse and 61 percent with a fruit fly. The remarkable thing is that, despite being very far apart in evolutionary time, we can still find a common signature in the genome of a common ancestor. And all of this is because all life that exists on earth has evolved from a single cell that originated about 1.6 billion years ago.

As Dr Brody says gleefully, ‘In a sense, we are all relatives!’

We are all related, but for a long time we have told our stories in different ways, not realising that your story is my story too.

It is a delight to be part of this book, and not just because I have written one of the forewords, taken one of the photographs, and am quoted on the back cover. But there is a way in which the story of the Trench family – and the story of the Guinness family in Rod’s previous book ( Guinness Down Under) – is your story and my story too … and not simply because of DNA tests or mathematical projections.

As Rod points out, the members of the Trench family not special because of an accident of birth or perceptions of inherited privilege. They lived a mixture of high and humble lives. They are part of the broad canvas of Irish history, and they must not be relegated to the margins and the footnotes of Irish social and political history to the footnotes of Irish history.

As I say in my foreword, the way we understand the place of landed, titled families in Ireland and their contribution to Irish life has changed profoundly in recent years.

This reappraisal has been helped, in part, by the Lthe works in refer to at the University of Galway and Maynooth University, and the work of historians in response to the ‘Decade of Centenaries’, including the Easter Rising in 1916, the War of Independence and the Irish Civil War.

In the past, writers were often dismissive of the roles of families such as these, caricaturing them as oppressive or capricious landlords, portraying them as quaint or eccentric, or finding them relative to nation-building narratives only when they included writers such as William Butler Yeats or George Bernard Shaw, or identified with nationalist causes, as with Henry Grattan, William Smith O’Brien or Douglas Hyde.

Too often, the Irish identity of these families was easily questioned or traduced, with pejorative labels such as ‘planters’ or hyphenated stereotyping such as ‘Anglo-Irish’ that doubted their identity and that implied Irish identity depends on particular cultural, linguistic or supposed ethnic backgrounds.

The recent and unsettling rise of populist racism in Ireland is a consequence of cultivating a definition of Irish identity that is neither broad enough nor tolerant enough, that is not visionary enough, to embrace the variety and breadth of ethnicity and culture that contributes to the mosaic making up the full, beautiful, diverse and rich picture of Irish identity.

The contribution of the Trench family to that mosaic is both rich and beautiful in its scope. They were French Huguenots in their origins, so offering an early contribution to linguistic and religious pluralism in Ireland. And their lives have embraced church life, and the cultural, political, architectural, educational and social life of Ireland.

Thankfully, this new book, lavishly illustrated, thoroughly researched and beautifully produced, introduces the truth that the stories of families such as this must never be confined to the margins and the footnotes of Irish social and political history.

In a blog posting last week, I quoted Leo Tolstoy (1828-1910) and his opening sentence in Anna Karenina: ‘All happy families are alike; each unhappy family is unhappy in its own way.’

As you read this book, you will find, contrary to Tolstoy’s oft-quoted saying, that the Trench family has, at times, been a happy family, like all happy families, and at times an unhappy family, ‘in its own way’ too.

But is that not so with all families? It is certainly true of the different branches of Comerford family too, as I know – at times, a happy family, like all happy families, and at times an unhappy family, ‘in its own way’ too.

But then, why should we be surprised? We all share many common ancestors, somewhere in the recent past – recent in terms of European and human history. Enjoy this book, for it offers insights into the stories of your family, and your story too.

We are continuing in Ordinary Time in the Church Calendar. The week began with the Eighteenth Sunday after Trinity (Trinity XVIII), and the calendar of the Church of England in Common Worship today remembers the life and ministry of George Bell (1881-1958), Bishop of Chichester, Ecumenist and Peacemaker.

I have a busy day ahead, speaking in Wesley’s Chapel, London, later this afternoon at the launch of Rod Smith’s new book, Clancarty: The high times and humble origins of a noble Irish family. But, before today gets busy, I am taking some quiet time this morning to give thanks, and for reflection, prayer and reading in these ways:

1, today’s Gospel reading;

2, a reflection on the Gospel reading;

3, a prayer from the USPG prayer diary;

4, the Collects and Post-Communion prayer of the day.

Tradition says the degrees of Jacob’s Ladder were 72 in number

Luke 10: 1-12 (NRSVA):

1 After this the Lord appointed seventy others and sent them on ahead of him in pairs to every town and place where he himself intended to go. 2 He said to them, ‘The harvest is plentiful, but the labourers are few; therefore ask the Lord of the harvest to send out labourers into his harvest. 3 Go on your way. See, I am sending you out like lambs into the midst of wolves. 4 Carry no purse, no bag, no sandals; and greet no one on the road. 5 Whatever house you enter, first say, “Peace to this house!” 6 And if anyone is there who shares in peace, your peace will rest on that person; but if not, it will return to you. 7 Remain in the same house, eating and drinking whatever they provide, for the labourer deserves to be paid. Do not move about from house to house. 8 Whenever you enter a town and its people welcome you, eat what is set before you; 9 cure the sick who are there, and say to them, “The kingdom of God has come near to you.” 10 But whenever you enter a town and they do not welcome you, go out into its streets and say, 11 “Even the dust of your town that clings to our feet, we wipe off in protest against you. Yet know this: the kingdom of God has come near.” 12 I tell you, on that day it will be more tolerable for Sodom than for that town.’

Shanah Tovah … the Jewish New Year celebrates the birthday of the universe

‘Celebrating the birthday of the universe’

Rosh Hashanah (רֹאשׁ הַשָּׁנָה‎), the Jewish New Year, celebrates the birthday of the universe, the day God created Adam and Eve. This year, Rosh Hashanah 5785 began yesterday evening at sundown on the eve of Tishrei 1 (2 October 2024) and ends tomorrow evening after nightfall on Tishrei 2 (4 October 2024). Together with Kol Nidrei (Friday 11 October) and Yom Kippur (Saturday 12 October), it is part of the Yamim Nora’im, the Days of Awe or High Holidays, and the 10 Days of Repentance.

Most synagogues and Jewish communities held Erev Rosh Hashanah services yesterday evening (Wednesday) and are holding Rosh Hashanah services today (Thursday). The central observance of Rosh Hashanah is blowing the shofar (ram’s horn), normally blown in synagogues as part of today’s services. Tashlich, in which people stand near a body of water and ask God to cast away sins, takes place in the late afternoon on the first day of Rosh Hashanah.

Rosh Hashanah traditions include round challah bread studded with raisins and apples dipped in honey, as well as other foods that symbolise wishes for a sweet year. Other Rosh Hashanah observances include candle lighting in the evenings and refraining from creative work.

Tonight is the second night of Rosh Hashanah, when the traditions include: prayer services in the synagogue, just like the first night; holiday candles, with the added blessing of Shehecheyanu; Kiddush over wine, with Shehecheyanu, if it was not said when lighting candles; a new fruit, enjoyed immediately after Kiddush; and a round challah, often studded with raisins. The festive meal, which is prepared after nightfall, typically does not include apples in honey, fish head, and the other symbolic foods enjoyed the night before.

Today’s Reflection:

The Gospel reading at the Eucharist today (Luke 10: 1-12) tells of the sending out of the 72, or the 70, depending on which translation we are reading and which manuscripts the translations give greater weight to. In the Eastern Christian traditions, they are known as the 70 or 72 apostles, while in Western Christianity they are usually described as disciples.

The number 70 may derive from the 70 nations in Genesis 10, but the number 72 may represent the 12 tribes, as in the significance of the number of translators of the Septuagint, the symbolism of three days (24 x 3), and understanding the meaning of 144 (12 x 12), to appear again in the 144,000 in the Book of Revelation.

In translating the Vulgate, Jerome selected the reading of 72. In modern translations, the number 72 is preferred in the NRSV, NIV, ESV and the New Catholic Bible, for example, but 70 figures in the NRSV Anglicised (NRSVA) and the Authorised or King James Version.

In number theory, 72 is the natural number after 71 and before 73, prime numbers. It is a pronic number, as it is the product of 8 and 9, it is the smallest Achilles number, as it is a powerful number that is not itself a power.

The number 72 is an abundant number. With exactly 12 positive divisors, including 12 (one of only two sublime numbers), 72 is also the twelfth member in the sequence of refactorable numbers. It has a Euler totient of 24, which makes it a highly totient number, as there are 17 solutions to the equation φ(x) = 72, more than any integer below 72. It is equal to the sum of its preceding smaller highly totient numbers, 24 and 48, and contains the first six highly totient numbers 1, 2, 4, 8, 12 and 24 as a subset of its proper divisors.

The number 144, or twice 72, is also highly totient, as is 576, the square of 24. While 17 different integers have a totient value of 72, the sum of Euler’s totient function φ(x) over the first 15 integers is 72. It also is a perfect indexed Harshad number in decimal (28th), as it is divisible by the sum of its digits (9).

In addition, 72 is the second multiple of 12, after 48, that is not a sum of twin primes. It is, however, the sum of four consecutive primes (13 + 17 + 19 + 23), as well as the sum of six consecutive primes (5 + 7 + 11 + 13 + 17 + 19). Also, 72 is the first number that can be expressed as the difference of the squares of primes in just two distinct ways: 112 − 72 = 192 − 172.

In science, 72 is the atomic number of hafnium, and in degrees Fahrenheit 72 is 22.22 Celsius and is considered to be room temperature.

Biblically, tradition says 72 is the number of languages spoken at the Tower of Babylon. The degrees of Jacob’s Ladder (Genesis 28:10-19) were 72 in number, according to the Zohar, a foundational work of Kabbalistic literature.

The conventional number of scholars involved in translating the Septuagint was 72, not 70, with six Hebrew scholars drawn from each of the 12 tribes. According to tradition, Ptolemy II Philadelphus sent 72 Hebrew scholars and translators from Jerusalem to Alexandria to translate the Tanakh from Biblical Hebrew into Koine Greek, for inclusion in his library.

According to Kabbalah, 72 is the number of names of God. In Kaballah, the Shem HaMephorash (שֵׁם הַמְּפֹרָשׁ) or ‘the explicit name’ of God is composed of 72 letters. The 72-fold name is derived from a reading of Exodus 14:19-21. Kabbalist legend says the 72-fold name was used by Moses to cross the Red Sea, and that it could grant later holy men the power to cast out demons, heal the sick, prevent natural disasters, and even kill enemies. This, of course, relates directly to the commission of the 72 in Saint Luke’s Gospel.

So, having turned 72 earlier this year, having arrived at my prime – or, at least, between two prime numbers – perhaps I am best served at room temperature. I am now a powerful number, suited to translation, ready to be sent out.

I once stayed at the Tamworth Arms at 71-72 Lichfield Street, almost directly across the street from the Moat House, the former Comberford family home. The Cock Hotel in Stony Stratford, where the choir of Saint Mary and Saint Giles Church regularly adjourns after Wednesday evening rehearsals, is at 72 High Street.

But what is there to look forward after 72?

When the long-serving Labour MP for Rochdale Sir Tony Lloyd earlier this year at the age of 73, the Guardian reported him as saying some years ago: ‘There’s this recognition that you only have a certain time left … I’m 70, and as such you think, “Well, I’m probably not going to be around in X years’ time, so use these years wisely. Use these days wisely.” That’s good advice for us all.’

Of course that’s good advice for us all. But surely there is more to look forward to than merely counting the X number of years ahead, to something that has more meaning than what is left of my mere temporal existence.

Today’s Prayers (Thursday 3 October 2024):

The theme this week in ‘Pray With the World Church’, the Prayer Diary of the Anglican mission agency USPG (United Society Partners in the Gospel), is ‘One God: many languages.’ This theme was introduced on Sunday in reflections by Rachel Weller, Communications Officer, USPG.

The USPG Prayer Diary today (Thursday 3 October 2024) invites us to pray:

Let us pray for a world where language diversity is celebrated as a testament to the beauty of God’s creation, and where people of all languages and cultures come together in solidarity, recognising that we are all children of the same divine creator.

The Collect:

Almighty and everlasting God,
increase in us your gift of faith
that, forsaking what lies behind
and reaching out to that which is before,
we may run the way of your commandments
and win the crown of everlasting joy;
through Jesus Christ your Son our Lord,
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.

The Post Communion Prayer:

We praise and thank you, O Christ, for this sacred feast:
for here we receive you,
here the memory of your passion is renewed,
here our minds are filled with grace,
and here a pledge of future glory is given,
when we shall feast at that table where you reign
with all your saints for ever.

Additional Collect:

God, our judge and saviour,
teach us to be open to your truth
and to trust in your love,
that we may live each day
with confidence in the salvation which is given
through Jesus Christ our Lord.
