Nice to make your acquantance Joseph Patrick :-)
What part of Belfast are you from?
As far as I can tell, my relatives were in East Belfast, but I'm not sure for how long. His Father was in Belfast between 1915-1919 at least. My Grandfather Joseph emmigrated to Canada in the earlier 1900's - he ended up in Toronto. He also served in the RIR briefly, as well as in the Canadian Forces.
Joseph only had one sister apparently, but could have had uncles and aunts in Belfast as well. Still working on the case :-) . If you have any clues, I'm all ears.
Great name!
Sheila
