Dear helpers,
many thanks for your replies.
The best I can offer at present is to say that Daniel Buckley's birth is likely 1826. This ascertained by early census in London.
Via 'Ancesrtry', there are Hurley's and Donovan's in my lineage (and of course, heaps of others...) However, one distant 'cousin', who has Buckley's in her tree, lists Kilmurry as a possible village of departure.
It is furher believed that 'Timothy' might be the father of Daniel together with a wife called Bridget - surname not positive.
It is unsure whether Daniel married in Ireland or London, whichever, his wife's name was Margaret.
All a bit vague I'm afraid, but your persistence is appreciated.
Regards all,
David
