Some time ago I received a copy of a journal kept by a sister of my gg grandmother, Anna Bell Garvie. Anna's father was James Garvie of Archterarder Scotland - also of Wisconsin, Iowa and South Dakota. In this journal she talks of how her father, James Garvie, received a package addressed to him but obviously not meant for him. They discovered another James Garvie on the Sissington Reservation who was actually the son of James' brother Stewart Garvie. Stewart Garvie came to the US with James in about 1844 but went to New Ulm Minnestota where he kept a trading post. He was married to a Native American woman with whom he had one son - James. Stewart was killed in an Indian uprising in 1862. The story goes that James was given to a white family on the Sissington Reservation. I have no idea whether this is accurate - I have never checked out the facts. Is it possible these are part of your family? If so, I have other information on the Garvie family you may be interested in.
