Hello Sandi,
My great grandfather is one of your Mitchells, Hugh, son of James Mitchell and Helen Kerr. Hugh emigrated from Tarbolton to LaSalle County, Illinois in 1888. In fact, I have a picture of his sister, Agnes Mitchell McConnell next to my keyboard right now. Do you have information about Helen and James' marriage? Or any specifics of James' parents, James Mitchell and Mary Cameron? Family information gives the date of James' birth as 10 April 1817, but haven't been able to document that.
Mary
