Samuel Stewart as father for Rebecca, we have now lots of hard confirmation for him on details:
We have him certified on:
1911 census: Married and right occupation and right area of Glasgow
1915 valuation roll: at Rebecca's birth address for 1922 and right occupation
1920 valuation roll: at Rebecca's birth address for 1922 and right occupation
His age, from the adoption papers fits the family we have found for him potentially. We also have a likely twin George who shows at the same address on the VRs 1915 and 1920.
We have an a/try tree for the family of Samuel that fits well to (not sure if you have had a response yet Mel from the tree owner).
Cannot find a marriage entry for Samuel to Harriet (as showing in 1911). Thought it might be an irregular type marriage too (although not certified

). Cannot also see anything in England for a possible marriage either.
Outstandings for Samuel:
Marriage to Harriett?
What happened to him after 1925 (cannot easily see a death for Harriett to help with this).
Did he remarry?
Death entry?
