Hello Monica,
Thanks for the encouragement. My 2nd cousin connects directly to Thomas Beattie Scott. His father is Thomas's eldest son. Unfortunate that he doesn't know very much. (I think that he probably knows a lot more than he realises,) but I have found it hard to keep him on track when asking questions of him.
I am already searching for another likely candidate. I found a family in Partick who also connect to Ballymena, Co. Antrim so maybe that is more likely. The father of this Thomas was a sawyer so I wonder did he progress to Manager by 1892?

I suppose that I have to look at all eventualities.
