Hi Monica
Thanks for the pointers, we've checked those leads already and it looks like it is Samuel.
The problem is that his parents, Hugh and Annie, along with his brothers James and John don't appear anywhere else. Tracing them is the key to going further back.
It looks like he left Dumfries sometime before he enlisted in Warrington which is next town to where he married and settled down in Widnes around 1892.
Thanks for your help, not sure where to go now!
Regards
Martyn
