Am searching for information on David FERGUS born in Argyleshire, Scotland in 1758. Minister of a Presbyterian (?)church there, supposedly he gave sermons in Gaelic. He married Janet Black, they both immigrated to Cumminsville, Ohio in 1822 with their daughter Janet Fergus Langland. David died in 1829, his wife Janet in 1845. Any information on the church in Scotland, David's parents, or anthing else would be helpful. Thanks.
