Howdy Mike!!

Thanks for the reply.

My ancestors were John M. DAVIS, Company E; and William D. KEITH, Company I, both of Titus County, TX.

Both of these men appear on various rosters of both the 18th and Morgan's Regiment TX Cavalry, each time in the same Company designation from each unit. The only one I know for sure is KEITH, whose name appears several times in the Heartsill book.
