Augustinus Cain/Catherina Boyd (G,G,Grandparents)

Hello,    My G,G,Grandparents were married 15th September 1851 at the Parish of Glinsk, Dioces of Elphin,Galway, Roscommon.They had a Son called James Cain/Kane He Died on11th March 1917. Partick, Glasgow, Scotland. His name was Spelled as Kane on his Death registers.His wife was called Bridget Fallon who also Died in Scotland 14th January 1921.Bridget was Married to James in Ireland and was  born there as well.

I haven't been able to find where Augustinus was Born, date of Birth or Death and the number of children in his Family. I believe he had another Son called John Born 14th June 1864 Roscommon,Roscommon,Ireland. Augustus Kane and Catherine Boyd as his Parents.

If you can help me it would be much appreciated.   Stay Safe.

All the Best
