Interesting. However your Alexander b 1835 is at least a couple of generations away from my James in Kilsyth.
Alexander Fin(d)lay and Elizabeth Easton were married in 1861. According to their marriage certificate, Alexander was the son of James Findlay and Helen Strachan and Elizabeth was the daughter of Alexander Easton and Jane Campbell. (This means, incidentally, that the online tree saying he was the son of James F and Janet Buchanan is wrong, and moreover it is wrong in significant facts that it took me about 30 seconds to prove wrong. In other words whoever posted that tree is guilty of seriously sloppy research, and not to be trusted as far as you could throw an overweight elephant.)
Helen Strachan's name is simply recorded as 'Helen Strachan', not as Helen Findlay M S [short for Maiden Surname] Strachan, which specifically implies that she was not married to James Findlay. Nor was Jane Campbell married to Alexander Easton.
In the 1841 census there is a household at North Main Street, Cumbernauld, comprising Margt Strahan, 45, cotton winder; Helen Strahan, 40, cotton winder; John Paterson, 24, labourer; Alexr Findley, 6; all born in Dunbartonshire. I have a feeling that I have come across this household before while following up my Paterson family, but eventually decided that he wasn't connected.
In 1851 Margaret Strachan, unmarried, aged 61, a pauper and cottom weft winder, and nephew Alexander Findlay, 16, coal miner, are listed in Wynd, Cumbernauld. Unfortunately both Margaret and Helen died before 1855, so there is not going to be a death certificate to get back another generation.
As for who James Findlay, father of Alexander, was, there might possibly be something in the Cumbernauld Kirk Session minutes that might give a clue to his identity, but I seem to recall, having looked at them, that they are not as comprehensive as some of the Kirk Session minutes I've read.
I've never heard of Robert Bryson's poems before. Do you have any more information about him, for example a date of birth?
By the way, Cumbernauld is not a county. It is a parish in the County of Dunbarton, which can also be referred to as Dunbartonshire (but never, ever 'Dunbarton County' or 'County Dunbarton'!)
