HI! I'm sorry, but I really don't know! My James Buchan was the son of James Buchan and Gorrie Stewart, and was from Scotland. I don't have information if he had any siblings, or if he did, if they were here or not. My mom has said that there were a lot of Buchan's and Buchannan's in the Rochester area, and that it's an old name there. Good luck, and maybe we'll be able to hook up information later!
