hi
thanks for your reply. Doyle is a very common name in county carlow, in the 1911 census for ireland there were nearly 1600 of them, in fact there were 15 john doyles that match you grandmothers cousin in laws age criteria too. if you knew a little more info, like the parish he was from, it would be a little more help.
but once again, thank you for the reply.
all the best
pete
