I would guess that B.K. Purkey continued to live with his father, John, and John's second wife (Mary Jane Laughery).The family seemed to migrate together, from Ohio to Illinois, and then the older B.K. Purkey children went to Missouri and Oklahoma but B.K. Purkey and the younger children went to South Dakota and Tacoma. B. K. Purkey and Joseph Francis Purkey (of the second marriage) may have been close as James Edward "Ed" Purkey, son of Joseph Francis was a neighbor and friend when I was a young child in Tacoma in the late 30's and 40's.My grandfather was J.O. Purkey, 2nd son of B.K.I think Bev Peterson and Wilma Meaden are two of the experts on Purkey history.
