Hello Andy
The info I have is John was born either 1856 or 1860 not sure which in Drummore, county Sligo, Ireland.
He married Ellen Kilcurran in 1883/84.
Ellen was born in Ballara, county Mayo 1855/56.
I don't know if they were married in Ireland or England.
They are on the 1891 census as living 59 Birkett Street, Liverpool.
They had 4 children, John, James, Sarah and Mary.
Mary was my grandmother.
A family member tols me that John jnr went to Scotland and died there.
I have no info regarding the remaining children.
I hope this helps.
Best wishes
Seira
