Hi Eileen, my father is also Brendan, son (obviously) of Bartholomew. I'd be delighted to give you any information at all on the family. Please send me an email to firstname.lastname@example.org
and we can correspond. I would also be very interested in photographs of the family, if you have them. Have you checked out the online census returns from 1901 and 1911? They give a lot of interesting information. I can send you the links after you email me.
I look forward to hearing from you.
