Hello Saroy,
Welcome to Rootschat! I have quite a lot of information on the Graham family. It was one of those lines which fascinated me, and so even though not my direct line I pursued it as far as I could. Some of my research is probably on this site somewhere, because I am sure I asked for help on it. I don't know much about Alexander Graham though, just that he was born in 1885 in England, and he had five sisters; Isabella, Sarah, Janet, Mary and Alice. All but Isabella, who was born in Glasgow, were born in England. There may be more siblings but I can't find them in the 1891 census to check for sure! Alexander was a dyeworks factory hand at Bonhill Dumbarton, Scotland in the 1901 census.
Hugh Graham was from Bute, originally a farmer from a long line of farmers, and Barbara was from Argyll. Hugh's father was Alexander Graham and mother was Janet Johnstone. Johnstones also owned farm land in Ayr. Barbara's father was Donald McDermid, a master blacksmith from Argyll and her mother was Catherine Clark. I can find no marriage record for Hugh and Barbara in England or Scotland. Barbara's sister Catherine married David Easton. That is one of the ways my line connects.
My Easton family were living in Bonhill for years, and Barbara and Hugh were both related to them through marriages, and I suppose that might be why the family settled there after returning from England, instead of going to Bute or Argyll. I don't know when or where Hugh died, so I am presuming he probably died in England and then Barbara and the children returned to Scotland.
I have more information on this family and am happy to share but I hope this is enough for now!
