Thank you for the replies, I don't know when or if he married , or even when he died. The military may be a possibility, in 1921. I have 3 army numbers, 7514, 8951, 94428. Do any of those tie in?
He was in the Royal Defence Corp half way through and beyond WW1 so may not have been living in Hartlepool, perhaps just using his brother's address as his home address
Regards, Bill.
