Gleavie Callen was a member of Zion United Church of Christ in St.Joseph, MO. He was probably married there. I was pastor of the church until last year. The complete church records can be found at the Northwest Geneaology Society (816) 233-0524. I came across your entry while looking into his involvement with the Ku Klux Klan.
Gleavie Jr. is currently in prison for a hate crime. His daughter whose name escapes me owns Modern Cleaners. Ann Lennington of Zion UCC is the current church president. She can fill you in on the family details. (816) 364-3261.
