I'm looking for information on my 2nd great-grandfather, John McBain, who was born in Banff, Scotland about 1812 (per 1841 census.) He married Jane Anderson in Huntly, Aberdeen in 1838. They lived in Marnoch, Banff, and all the children were born there (Isabella, John, Peter, and William). He died between 1841 and 1851, as his wife is a widow in the 1851 census. I would appreciate any information.
