Think I need to apologize for the brevity of my initial response. To me, the "trail" seemed clear and I felt others would have traced the family. Reviewed a few public family trees and learned I am/was mistaken. His parents, William Franklin Gates/Nancy Harrell, have find-a-grave memorials in Trinity. His father filed a Civil War Pension application, 1 Jun 1914. Unfortunately, he died (2 Mar 1918) prior to approval of his request. Much person info found on the application such as: his place/date of enlistment, birth locale, and an affidavit completed by his brother.
