Hi

I'm trying to find any descendants of John McWilliams and Jean/Jane Main (Mean).

They had 5 children: James (1802), Robert (1803), Elizabeth (1805), John (1814) and Susan (1816).

I am descended from Robert but don't know if there are any descendants from any of his siblings about. I'm also trying to find what happened to his 2 children from his first marriage - Agnes (1833) and William (1835), both born in Penninghame. The last I know of William was that he was serving in the army in India
