My data has William Sylvester Snodgrass b/1838 d/1862 as s/o James M. Snodgrass and mary Ann Whitaker. James M. S. was s/u of David S. and Mary AQnn Meek. David s/o Joseph S. and Mary Ann Hutton. Joseph S. s/o John S. Jr. and Nancy Miller. John s/o John Sr. and Eliz. ?? Juniors and Seniors can be confusing because often the junior has a junior and then he becomes a senior. Even a junior can be a junior to an uncle with same name. That makes the name of the wife and mother important!!! jane G.
