You mentioned finding possible brother Thomas who died in 1923 in Bridgeton.
There is one other death. Possibly a sister:
Catherine CONNER
43
Mother's maiden name WINTERS
1899
644 / 1 / 982
Bridgeton
There is no second surname indexed so possibly unmarried?
Monica
That's Owens sister alright Monica, on her death cert she is named as Catherine Mcoll.
The story is starting to come together now,
My G/Grandparents, James Docherty and Margaret Gallagher were married in 1879,
Margarets parents are listed as Daniel Gallagher, Farmer, and Ellen Gallagher M.S.Connor.
Witnesses to the marriage were, Owen Connor and Bridget Mcoll,
Thanks to the 1921 Census I found out my G/Grand father was from Derry and my G/Grandmother was from Cornamucklagh Co Monaghan.
I was able to trace the Gallaghers to the 1901 Irish Census where Daniel Gallagher was still living with his son Hugh in Cornamucklagh,
I'd like to find out if the Gallaghers and the Connors are from the same or near townlands in Co Monaghan.
I'll park it here for the night as my brain is starting to scramble,
Thanks again for your time and knowledge.
Regards, John.
