Hello Heywood,
you are correct . My information from Scottish records.
Year of birth is based on Scottish census returns . Giving his year of birth as circa 1845/6. His parents names are from his marriage certificate in Glasgow from 1868 and these are confirmed from his death certificate issued in Glasgow in 1882. The only minor difference being the alternative spelling of his mothers name . This was common with Irish names in Scotland.
So far no sign of a birth though , or any other children to his parents. Perhaps Patrick was Denis as none of Denis' children of which there were 7 were named Patrick. Denis , Matthew and Michael were the three boys, all born in Glasgow.
Any suggestions would be appreciated,
Baird
