Your Horace's parents were John Wiley and Eddie Nance Minchew/Minshew from Barbour County, Alabama. John was one of eight children of Merrick Nichols & Elizabeth Ann Graves Minshew that I know about. This family came to east Texas prior to the 1880 Titus County Texas census. Merrick and Elizabeth are buried at Macedonia Cemetery just outside Pittsburg in Camp County. Supposedly John Wiley is too, but I have yet to find him or his wife there. Granted, there are several dozen graves there that are unmarked or only have a rock or a post stuck in the ground to indicate someone's final resting place. One of those could be his. No one knows.
John and Sarah Amanda Collinsworth Minchew never made it to Camp County. They lived predominately in Melrose, Texas in Nacogdoches County. They are part of the family also from Alabama, but they may or may not be related to us.
