Hi Paula
Prompted by your recent posts, I did a little research on Rootsireland and found the Thomas Donoghue-Jane Keogh church marriage record in November 1891. She was, indeed, the sister of my great grandfather Michael Keogh. Happily, the marriage record lists both her parents, John Keogh and Julia Smyth. I already had them for Michael, so it is conclusive. I found the baptismal record for Thomas's and Jane's son Thomas in September 1895 so you were right, back in May, in identifying the family in the 1901 census when young Thomas was listed as 5 years old. The marriage record shows that Thomas Senior's parents were Patrick Donoghue and Anna Whelan. This gives me a step back towards (hopefully) one of the Donoghues you listed as descended from Michael Dwyer's sister Catherine. Unfortunately, I haven't been successful in finding a marriage record on Rootsireland for Patrick and Anna so far. I may have better luck on FamilySearch.
Thanks for getting me back on the track of this side of the family. I will let you know if I discover any more.
Best regards
Dermot
