I thought I'd let you know that Braddock Tryon show up in the 1860 census in Madison Township, Johnson County, Missouri with the William S. Gregory family. This is a brother to Nancy Gregory Tryon. Edwin A. Tryon appears in the 1860 census of Canton Twnship, Lewis County, Missouri in the William Gregory family. This would be William Davis Gregory, Nancy Gregory Tryon's brother, Thomas Inglefield Gregory's son (i.e. her nephew).
