An update for anyone interested;
My grandfather's (James Comer) birth wasn't registered, or at least if it was, the registration never made it to the GRO from the local register office. We got a certified copy of his baptismal record, and the GRO issued a retrospective birth certificate..... only 136 years after the event!! My brother has applied for his foreign-born registration (so he can get an Irish passport) and is still waiting to hear about that.
In the meantime, we have both had DNA tests done and appear to have 4th cousins with Donlon/Donnellan/Donelly surnames in their trees in the correct area of Co Galway. My gt grandmother's maiden name was Donlon (and variants) from this area of Co Galway which matches with my paper trail, so I'm confident all the research is correct and I haven't been barking up the wrong tree.
