My great-great grandfather was Harry Hickey who was a confederate in the Civil War and was in a Union Prison Camp in Troy, NY. He had a son, (James H.Hickey - my great grandfather), and a daughter, name unknown. In Troy, he re-married and might have had other children. His son, James, ran away during this time and moved to Colorado in the latter part of the 1800's.
Could Mary be Harry's daughter from the first marriage? Has anyone heard a part of this story?
