Thank you everyone, to be honest I'm just in awe at your abilities with lateral thinking! It looks as if the Barnaby family as such arrived in Wales from Shropshire in the 1800s, so there is quite likely to be connections between all of them, which is excellent from my point of view. I'm trying to trace the father of an illegitimate child born in 1931 in Rhymney and the name mentioned in old paperwork is Barnaby with no other details. I'd like to narrow it down to as few "potentials" as possible and then see what else I can come up with. I have DNA to work with so I will just have to see what matches where. Thank you for the input, it's made the fog much clearer!
