I have John Elder on the 1901 English census. He is a Sergeant in the Royal Artillery. He is stationed in the Citadel Plymouth.
According to the census he was born around 1868, and it says County Derry as his birthplace.
My question is, does anyone know how I can find out if he joined in Ireland or England.
I think his parents were James Elder and Rebecca Bailey, but no proof of that.
Any help greatly appreciated.
