Looking for info of the Abner Strother Gaines this is how his tombstone reads, corp of engineers army pacs of Tennessee 1833 -1905 Burried in Stateline, MS Abner is the sone of George Strother Gaines, Pioneer, statesman, in both the BAMA and MS Legislature,Indian agent, he was cousin to US president Zachary Taylor, and Sarah Knox Davis who was Jeff Davis Wife . What does the PACS stand for? Is his dad, the man the Gaines Invincibels 46th MS infantry "Wayne County" and the Gaines Warriors "Greene County" are named after?
