My Weatherford ancestors were in the 17th Tennessee Cavalry Battalion (later the 9th Mississippi Cavalry) and the 12th Mississippi Cavalry Battalion. From the beginning of 1864, these units were in the same brigade as Perrin's Regiment. I did a family history that covers the units. While not all of it would be pertinant to the 11th Miss Cavalry, the part beginning with 1864 would. If you would like a copy, send me an e-mail address and I will forwarded it to you by e-mail.
