my aunt Verna Horning, daughter of Alma Butterfield Horning. Alma's father was the older charles robert butterfield (1844-1885).
Charles Robert Butterfield parents were Abel Butterfied and Caroline Sprout. Many people on various family tree sites say that info is incorrect. But Verna's husband did extensive research at the LDS library because he is an LDS member and has access only members have. He has this info with documentation.
