How can I determine which information below is the most correct for my ancestor William W Watkins, b. 11-17-1825, of Sabine County, TX? Search engine results usually show W W Walkins, even though the "t" is crossed in the picture.

1) W W Watkins served in Crump's Cavalry (Lane's Cavalry, First Partisan Rangers); Frontier Battalion, Cavalry; Gano's Squadron, Cavalry in 1863 and 1864.

2) William W Watkins' Application for Headstone, mentioned Lane's Regiment, Watterhouse's Company, Texas Cavalry, Private, for McMahon Chapel in 1933.

3) William W Watkins' Headstone at the McMahon Chapel, shows Lane's Texas Cavalry, Company M, Private.

Several of his descendants are buried next to him, including my g-grandfather.

Where can I find more information about him and where he may have served during the 1863 and 1864 time period?
