Hi,
Sorry your name is not posted here. However, greetings from Nepean, Ontario, Canada.
This is a long long shot in the dark, so please bare with me while I go the long way around to ask if you have done a DNA test anywhere? I have I think two lilligitimate births between 1847 and 1877 (the second being my paternal grandfather) in Whitechapel, London. His mother being part of my other Irish (Cork) heritage on my Father's side of the family. To cut a long story short, I did Y line DNA test and ended up with the closest contacts being "Kavanaghs" from Wicklow and Wexford and our best guess 1750 as a so far unidentified (unidentifable) common ancestor.
So have you done a DNA test somewhere, are you on GedMatch? Obviously I am looking for potential Kavanagh matches in Wicklow/Wexford circa 1830.
My thanks
John
