I am searching for any information regarding my great-grandfather, surname Posey. He delivered U. S. mail between Durant, OK and Denison, TX in the 1880s, and was robbed and murdered on a mail run. His wagon was found in the Red River. There was a suspect found in Bryan County wearing my ggf's Masonic ring but nothing ever came of it. He had four children, Addie, Laura Elizabeth, Ellis and an infant. His wife and infant were burned to death in a tragic fire. Laura Elizabeth is my grandmother and she was born in Weatherford, TX and raised by relatives.
