Martha Ellen Barr (12/6/1863 - 2/13/1934) married Smith McGinnis Potter on 12/7/1879 in Bates Co. Missouri. They are my paternal great grandparents.
My gg-grandfather Samuel Gray Potter and Pardon are likely brothers. Smith M. Potter is Samuel's son. I suspect they were cousins, but still doing early research. If you have info on Pardon and Uriah, please contact me. Interesting lot, the Potter family.
