Hi sorry it took so long to answer. I just got an alert from Ancestor.com with your information.
William Glen Jett was married to Clarinda Kuykendahl. His father in law was Wiley Kuynendahl. He fought (with the confederates)at the battle of Glorieta (New Mexico territory) pass. The battle was terrible & some men were buried where they died. It was a "...little known..." battle of the Civil War. William Glen Jett & the other surviors of the battle of Glorieta Pass (NM territory): returned to Texas. The trip back was fraught with danger & difficult passage with little food to be found on the way. William Glen Jett became a Texas Ranger. His gun is in the museum at "The Alamo." He had a brother names Steven. I'll have to look for further information in the few family records I have of him.
