My first genealogy project of 2020 involves tracing the descendants of my third-great-grandparents, Jeremiah Keogh and Jane Crosby, mainly to see if any of them can be identified among my mother’s list of DNA matches. In addition to their daughter Maryanne, who was my great-great-grandmother, Jeremiah and Jane had three sons - Thomas, Martin and John. This post is about Thomas and his descendants.
Thomas Keogh married Charlotte Lysaght (sometimes known as Charlotte Mooney after her stepfather, John Mooney) in St Laurence O’Toole’s church in Dublin city on 13 April 1866.
Barely one month later, their eldest son was born. He was christened Jeremiah Richard Keogh in St Andrew’s church, on the other side of the River Liffey, on 21 May 1866. He was named after both his grandfathers, Jeremiah Keogh and Richard Lysaght. As far as I can tell, Jeremiah Richard was the couple's only surviving child.
Soon after he was born, Thomas and Charlotte returned to O’Toole’s parish, where three additional children were baptised - Thomas Michael born in 1868, died in 1869, Catherine Margaret born in 1870, died in 1880 and Martin, born in 1872, died that same year.
Both Thomas and Charlotte died relatively young themselves. Charlotte got nephritis (inflammation of the kidneys) and died at home, at 7 Ossory Road, on 15 March 1895, stated age fifty years. Thomas died of bronchitis at his son Jeremiah's home, at 14 Abercorn Road, on 12 May 1898.
Jeremiah Richard Keogh worked as a bricklayer, like his father and grandfather. He married twice. His first wife was Mary Cassidy, who he married in 1890 and with whom he had five children. Mary died of phthisis (tuberculosis) in 1902, and in 1903 Jeremiah married Christina Griffen. They made their home in Caledon Road, Dublin, and had six more children. Jeremiah died on 18 March 1940, having suffered from hemiplegia (paralysis of one side of the body) for ten days.
DNA evidence:
After tracing Jeremiah's many descendants, only one DNA match became apparent. This lady shares a 27 cM DNA segment with my mother and 17 cM with Mam's maternal first cousin, and shares a different 15 cM DNA segment with my maternal uncle.
A relationship calculator estimates their connection as either third cousins once removed, fourth cousins, or second cousins twice removed. And, it turns out they're third cousin once removed. Our new cousin's grandmother was born Charlotte Keogh, Jeremiah's second-eldest daughter. It all fits!
And it provides genetic evidence that Thomas and my Maryanne were siblings, and helps to link me scientifically with my third great-grandparents.
Jeremiah Richard's children were:

This is a great example of how good basic research can be backed up by the science of DNA. Visiting from #geneabloggers Shared
ReplyDeleteThanks Jennifer, it is cool when DNA matches help confirm the paper trial.
DeleteGreat sleuthing, Dara! I hope this post finds some cousins for you. :-)
ReplyDeleteThank you Elizabeth, I do love meeting cousins.
