Hi again. I spent several hours in the TSLAC building in Austin and discovered a book named The Confederate Army of New Mexico, in which the 5th Mounted Volunteers have a chapter. Under "Privates" I found: Kerr, T.P., age 21; and Kerr Augustus Hollowell, 20 (elected third sargeant March 18, 1862). Under "Officers" I found Kerr, M. P., age 20, second corporal (elected first corporal Dec. 23, 1861; elected first sargeant March 18, 1862; in El Paso hospital with dysenteria June 12-20, 1862). I can't remember the full content of our previous correspondence, but you do know that the 1850 Washington County census lists A. H. Kerr (spelled Karr in that census) as one of the children of A. T. Kerr/Karr and P. A. Kerr/Karr, both born Georgia. A. T. must be Augustus Thompson Kerr, son of Hugh and Lucy Thompson Kerr. Also listed on that census is Thompson Kerr, whom I believe now to be the T. P. Kerr listed on the CSA register for the 5th Calvary. Now to supposition: almost everyone in that regiment is from Washington County, and their names are found on the census. Given that fact, and the fact that my gggrandfather, Monroe Pierce (MP) Kerr stated he served in the CSA with three of his brothers, is it too big a stretch to think he, Thompson (TP) and A. H. are brothers? Lets try sharing again. Every clue helps.
