John Montgomery married Mary Eleanor Davis in Jefferson Co, IN Jan 1, 1847. His sister, Eliza, married Samuel Colbert in Jefferson Co 25 Feb 1847. I believe, based on the "Wills and Administrations" posting, they may be the children of William Montgomery and Mary, his first wife. I would welcome more information about the Montgomery family. John and Eliza were both living in Hancock Co, KY for the 1850 census.
