I have info on both men, will deal with 1st Cpl Thomas J. Reagan also known as 1st Cpl Thomas (R.) Reagan for now. He enrolled Feb 17,1862 at McKinney, Tx, at age 24, by William Fitzhugh for a period of 12 months, his horse was valued at $150.00 and his equiptment at $30.00. One of his records show that in Nov. of 1862 he was "waiting on sick". It doesn't say where, but it may have been at Camp Nelson, as the time and his unit placement are right. In a report by Gen. H.E. McCulloch he is listed as wounded in the shoulder during the engagement of Milliken's Bend, La. on June 7, 1863. He is not listed on any further rolls, so he probably died of his wound.
Do you know of a lady by the name of Mrs Roy Bush from San Antonio, Texas? She wrote a letter on July 22, 1953 (yes 1953) asking about his military records, and some General replied to her letter in August of 1953. She must be or have been some kin to Thomas J.(R.) Reagan, and she may be kin to you. If your ok with it send me your e-mail, I'm at convertiblecowboy@suddenlink.net
