Yes I did notice Catherine died in the poor house not sure where you live Mitchell Library Glasgow have records might be worth checking to see if Catherine applied for poor relief .There were several deaths for a Thomas McGuire unfortunately not showing mothers maiden name

Yes, I'll get to the Mitchell Library soon to see what I can find. I did get the death certificates for the Thomas McGuires without maiden names but none seem to match him. I've also found a census record from 1901 showing (Francis) John McGuire aged 16 which would match up with my great grandfather. There's also a Sarah McGuire too. But no Thomas.
