I am looking for information on the Confederate Cavalry regiment my Great-Great Grandfather was in. His name was John Caldwell Calhoun Moore. In his pension application, he states he was a Lieutenant in Hardeman's Texas Cavalry Regiment; no number is given.

His wife, Louisa Anna Dodson Moore,in her application to get his pension after his death, did not remember anything about his regiment except for the fact that he was a Lieutenant and that his regiment was founded by a Captain Ferrell from La Grange, Fayette Co., Texas. She also stated he was in the war from 1862-1865

Any help would be most appreciated!
