Dear Gerard
I think you have given me a positive lead, as it never dawned on me that the farrell aunt was nee brophy and that she is my williams sister, looking at the 1911 census for this family, I can see that she was born around 1874, so she will definitely be on the civil records, and then i just trace whatever parish record relevent to her back, and voila, I find william!!! If only it will go like that, this family tree stuff is never ending, but without your message today i would not have made another step forward. Thank you. I am in Dublin, and regularly in the LDS, and occasionally in NLI, if i can reciprocate in some small way, please don't hesitate to ask.
all the best
pete
