Which Jacob Family are you researching?
Connection between Perryman and Jefferson Family.
My gr x 2 grandparents are Hector and Kitty Perryman. He had two half brothers William McIntosh and Jacob Perryman. John Jefferson and Melinda Cow Tom are my gr x 3 grandparents. Their son John Jefferson Jr married Hector and Kitty Perryman's daughter Mary Alice Perryman.
#277 Hector/Kittie = Mary Alice (Perryman) Jefferson married John Jefferson Jr son of John Jefferson and Melinda (Cow Tom) Jefferson
Census Card # 1077/Roll #4086 = Jacob Perryman. He served in the Civil War as a Union Soldier in the 1st Indian Home Guards Regiment, Kansas Infantry Company C as a Private. All of Jacobs male children (Census Card #’s 494,1056) changed their surname to Jacobs while Hectors male children retained their Perryman surname.
Hope this helps
