Hi again & thanks Dathai, we've been in touch before some years ago!
Ok the tree on LDS is my cousins and we have a few conflicting dates

anyhow I get frustrated and put my GGrandfather away in my filing draw and every now and then try to relight my fire hoping something new will have appeared haha but no.
I now believe that the 2 children born to Bridget Armstrong & MICHEAL (not James) Callaghan are my GGrandfathers siblings.
I found Bridget's death in 1907 Urlingford so I sent for the certificate which states her daughter Katy/Catherine as witness. Also found Bridget & Katy are living together in the 1901 census Urlingford.
I could send for either Katy or Johns birth cert but Im not sure if Id be wasting my my money, whats your thoughts?
