Calvin Coker born in Arkansas 1847, or there about. Moved to Texas, married Martha Melvinia Rippetoe or Melvinia Rippe, don't know for sure what Grandma's maiden name was. They were married about 1866. Moved to Oklahoma near Hugo in Choctaw Co. after 1900 I think. They lived in several places in Tx including Delta Co. maybe near Klondike. some of children were Martin, John, Robert, Otis, Elizabeth, Obilee and others but not sure of their names. I think Ed and or Earl. I might be able to find something in papers but don't know.
