Hi, I work for Geni and I'm at the NGS conference with grandchildren of Josie, Ann and Jim McFerrin. According to their information the parents of Josie and sibling are John / Jack Satterwhite and Sarah Ann Redford.
Jim and Ann also pointed out that sibling Francis is marked as born in 1760 which would be much too early for Jose 1859 (they say 1861).
