The intriguing stories that
can emerge from research
into Irish Jewish genealogy
and family history

Stuart Rosenblatt is the leading expert on Irish Jewish genealogy and has been described as ‘a beacon of light for future generations’

Two statistics have been drawn to my attention in recent days that I find intriguing.

An analysis of DNA findings suggests that nearly half of the population of Ireland may carry Jewish ancestry, according to Stuart Rosenblatt, the leading expert on Irish Jewish genealogy.

In a 20-page study published in the IOSR Journal of Humanities and Social Science (Vol 26, Issue 6, Series 10, June 2021), Elizabeth C Hirschman Hill, Richmond Gott Professor of Business Department of Business and Economics, University of Virginia-Wise, says DNA evidence suggests many Lowland Scots and Northern Irish people have Jewish ancestry.

She says she has used the newest genealogical DNA methodology of phylogenetic trees to identify a large population of Jewish descent in the Scottish Lowlands and Northern Ireland. She proposes that the majority of these ‘Lowland Scots and Northern Ireland colonists’ were likely crypto-Jews who had arrived in Scotland in three phases: with the arrival of William the Conqueror in 1066; after the expulsion of Jews from England in 1290; and after the expulsion of Jews from the Iberian Peninsula in the 1490s.

She believes evidence is found that both the Ashkenazic and Sephardic branches of Judaism are present among these Lowland Scot and Northern Ireland residents. I was interested that the family names she included in her study are Hunter in Ireland and Kirkpatrick in Ireland and Scotland.

I am not convinced of her methodology, deductions or arguments, and she seems to be unsure about the understanding of lineage of Levites and cohanim in Jewish communities. Nevertheless, it is a curious hypothesis.

The leading expert on Irish Jewish genealogy, undoubtedly, is Stuart Rosenblatt. He also says DNA findings now suggest that nearly half of Ireland’s population may carry Jewish ancestry.

On a mailing list I am part of, Stuart was described earlier this week as ‘a beacon of light for future generations’ whose ‘quiet determination preserves the memory of a people.’

Stuart Rosenblatt is the founder of the Irish Jewish Genealogical Society, and he was the newly-elected president of the Irish Genealogical Society when I was invited to give a lecture in Dún Laoghaire on ‘The Comerfords in Ireland: Disentangling Myths and Legends to Find True Origins’ over ten years ago (10 February 2015).

Stuart was a genial host, and we had wonderful conversations about Comerford genealogy and Jewish genealogy and shared our thoughts on genealogical methodology that evening as he brought me to and from Dún Laoghaire Further Education Institute. We have both collaborated on research for programmes in the popular genealogical television series, Who Do You Think You Are?.

It has been said among genealogists and within the Jewish community in Ireland that never before in genealogical research has anyone attempted what Stuart has achieved – recording the full story of an ethnic Jewish minority across an entire nation, spanning all 32 counties in his Irish Jewish Roots project.

Over more than three decades, he has meticulously compiled an archive of 75,771 names, each entry containing up to 110 pieces of information. His work now fills 22 bound volumes, with copies in the National Library of Israel in Jerusalem, the National Library, the National Archives Dublin, the Irish Jewish Museum and the Genealogical Society of Ireland.

This archive is more than genealogical data – it is a bridge to identity. It aids descendants of Irish Jews worldwide, whether they seek to trace relatives, secure an Irish passport, or walk the streets where their ancestors once lived.

The records show many lineages go back 300 years, and the oldest stretch as far back as 1555, when most Irish Jews were of Spanish-Sephardic heritage. Today, most Irish Jews can be traced back to Eastern European Ashkenazi Jews from Lithuania and neighbouring nations who arrived in Ireland the 1870s.

Stuart has travelled throughout Ireland, gathering overlooked sources such as school registers, midwife journals, nursing home logs, memorial notices, and prayer books with handwritten inscriptions – fragments that official records rarely capture. His dedication is unwavering and at 81, he still works on it at his own expense, joking that his commitment is ‘eight days a week.’

His project began in the Irish Jewish Museum, housed in the former Beth Hamedresh Hagadol Synagogue on Walworth Road, Portobello, in Dublin’s ‘Little Jerusalem’. There he came across dusty boxes filled with genealogical fragments, and ouft o this chaos he created 16 separate databases, later merging them into a searchable programme.

Since then, the archive has become a living resource, accessed by scholars, families, and institutions worldwide. His work has supported television research, inheritance cases, DNA studies and countless personal projects.

‘Circumcision records are rare,’ he told an interviewer for the Jewish News Service, ‘although in one record, Revd Abraham Gittleson, in an entry under ‘Observations’ noted that the nurse fainted! And that stood out!’

The second statistic that has come to my attention in recent days and that I find intriguing is found in an analysis of the figures in the 2021 census for the Jewish population in England and Wales by ethnic group and nationality.

The figure for the total the Jewish population in England and Wales in the last census is 269,293, or 0.5% of the overall population. Of these, 230,399 (85.56 per cent) are classified as white, and among them 927 (0.34 per cent) are described as Irish, and 161 (0.06 per cent) as Irish Travellers.

For the first time, the census category ‘Irish Traveller’ was introduced for the first time in 2011, and in the 2021 Census of England and Wales, the Gypsy/Irish Traveller community numbered 67,757, or 0.1% of the population. But it means that 1.36 per cent of Irish Travellers identity themselves or declare themselves as Jewish, so that the proportion of Jews in the Irish Traveller population in England and Wales is higher than the proportion of Jews in the total population in England and Wales (0.24) or the proportion of Irish Travellers in the total population in England and Wales (0.1).

The other intriguing figures in those census returns in England and Wales include (and I am selecting randomly) 178 Roma Jews, 159 Chinese Jews, and 422 who say they are Arabs.

These are intriguing and fascinating breakdowns of statistics. But behind each statistic and each figure is a human story, and I’d love to hear more of those stories. Who are the Irish Traveller Jews living in England today? Where do the Chinese Jews comes from? How do the 422 Arab Jews feel about events over the past two years in Gaza, Israel and the West Bank?

We are continuing in Ordinary Time in the Church Calendar, and this week began with the Seventeenth Sunday after Trinity (Trinity XVII, 12 October 2025). Today the Calendar of the Church of England in Common Worship and Exciting Holiness remembers Saint Ignatius (ca 107), Bishop of Antioch, Martyr.

Before the day begins, 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 short reflection;

3, a prayer from the USPG prayer diary;

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

Luke 12: 1-7 (NRSVA):

1 Meanwhile, when the crowd gathered in thousands, so that they trampled on one another, he began to speak first to his disciples, ‘Beware of the yeast of the Pharisees, that is, their hypocrisy. 2 Nothing is covered up that will not be uncovered, and nothing secret that will not become known. 3 Therefore whatever you have said in the dark will be heard in the light, and what you have whispered behind closed doors will be proclaimed from the housetops.

4 ‘I tell you, my friends, do not fear those who kill the body, and after that can do nothing more. 5 But I will warn you whom to fear: fear him who, after he has killed, has authority to cast into hell. Yes, I tell you, fear him! 6 Are not five sparrows sold for two pennies? Yet not one of them is forgotten in God’s sight. 7 But even the hairs of your head are all counted. Do not be afraid; you are of more value than many sparrows.’

Today’s Reflections:

There is story from China in the 1950s of how Mao ordered the extermination of several pests, including sparrows. But it was a campaign that led to an environmental disaster.

It all seems to have started off with what looked like a good idea. Mao argued that nature should be fully exploited for production, and building up industry would not only modernise China but also build up an urban proletariat that would provide a solid support base for the Chinese Communist Party.

The Eurasian Tree Sparrow was singled out in particular because in was eating grain seeds. Chinese scientists calculated that for every million sparrows killed, there would be enough food to feed 60,000 people.

Chinese people took to the streets in great numbers, clanging their pots and pans or beating drums to terrorise the birds and prevent them from landing. Nests were torn down from trees, eggs were smashed, chicks were killed, and sparrows were shot down from the branches.

School children, civil servants, factory workers, farmers and soldiers were all mobilised in the campaign, along with hundreds of thousands of scarecrows and colourful, fluttering flags.

Young people trapped, poisoned and attacked the sparrows, children and old people kept watch, and free-fire zones were set up for shooting the sparrows.

Hundreds of millions of sparrows were killed in this campaign of destruction, and the sparrow almost became extinct in China.

But as well as eating grain, the sparrows also ate insects in great numbers. Without the sparrows to eat the insects, the insects gobbled the crops that the sparrows had nibbled at. Crop yields dropped to an all-time low and rice growing faced a disaster.

When Mao called off the Great Sparrow Campaign, it was too late. The situation got progressively worse, locusts swarmed the countryside, and the loss of the sparrow contributed to widespread famine from 1958 to 1961, when 30 million people or more died of hunger.

It still remains a chilling reminder of the dangers that can be created by any changes to an ecosystem.

The sparrow in this morning’s Gospel reading (Luke 12: 1-7), is, in the original Greek, στρουθίον (strouthíon), any small bird, especially a sparrow (verses 6, 7; see also Matthew 10: 29). The Hebrew word צִפּוֹר (tzippor) comes from a root signifying to chirp or twitter, a phonetic representation of the call-note of any passerine or sparrow-like bird.

This word occurs more than 40 times in the Hebrew Bible. In English translations, it is often rendered as ‘bird’ or ‘fowl’ and denotes any small bird, both of the sparrow-like species and such as the starling, chaffinch, greenfinch, linnet, goldfinch, corn-bunting, pipits, blackbird and song-thrush.

However the name is translated from the Hebrew or the Greek, these birds are found in great numbers in the East Mediterranean and are of very little value, selling for the merest trifle.

The blue thrush is probably the bird to which the psalmist alludes to – ‘I lie awake; I am like a lonely bird on the housetop’ (Psalm 102: 7) – is a solitary bird, setting itself apart from the company of its own species, and rarely more than a pair are seen together. The English tree-sparrow is also very common, and may be seen in numbers on Mount Olivet and about the sacred enclosure of the Mosque of Omar.

There are great numbers of house-sparrows and field-sparrows who make their nests just where people do not want them: they block stoves and water-pipes with their rubbish, and build in the windows and under the beams of roofs.

The sparrow mentioned several times in the Bible often symbolises insignificance and the providential care of God. The sparrow represents the humble and the lowly. Despite their perceived insignificance, their nuisance value, and the cheap price they sell for, the Bible uses sparrows to illustrate God’s attentive care for all his creation. And without them, without each and every one of us, the whole ecosystem of God’s beautiful creation is severely threatened and endangered.

Even the sparrow finds a home,
and the swallow a nest for herself,
where she may lay her young,
at your altars, O Lord of hosts, my King and my God (Psalm 84: 3).

Today’s Prayers (Friday 17 October 2025):

The theme this week (12 to 18 October) in Pray with the World Church, the prayer diary of the Anglican mission agency USPG (United Society Partners in the Gospel), is ‘A Life Dedicated to Care’ (pp 46-47). This theme was introduced on Sunday with a programme update on Sister Gillian Rose of the Bollobhpur Mission Hospital, Church of Bangladesh.

The USPG Prayer Diary today (Friday 17 October 2025, International Day for the Eradication of Poverty) invites us to pray:

Lord God, poverty is not your plan. We pray for an end to poverty in all its forms, that every person may live with dignity and hope.

The Collect of the Day:

Feed us, O Lord, with the living bread
and make us drink deep of the cup of salvation
that, following the teaching of your bishop Ignatius
and rejoicing in the faith
with which he embraced a martyr’s death,
we may be nourished for that eternal life
for which he longed;
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:

God our redeemer,
whose Church was strengthened by the blood of your martyr Ignatius:
so bind us, in life and death, to Christ’s sacrifice
that our lives, broken and offered with his,
may carry his death and proclaim his resurrection in the world;
through Jesus Christ our Lord.

Collect on the Eve of Saint Luke:

Almighty God,
you called Luke the physician,
whose praise is in the gospel,
to be an evangelist and physician of the soul:
by the grace of the Spirit
and through the wholesome medicine of the gospel,
give your Church the same love and power to heal;
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.
