Various transcribed musters have mis-spelled my ancestors names in Company D 10th Texas Cavalry. Joseph DeKalb Mathis, William Nicholas Mathis & Jacob Lewis Mathis were all brothers serving together and were from Upshur County, Texas. Variously they are misspelled as J.D., W.N. and J.L. Mathews instead of Mathis. Any information you may have on these brothers will be greatly appreciated.
