James M. Preston who was married to Vinea Sparks was my great-grandfather. My grandfather was one of his sons by her, Forrest K. Preston. I have a very old genealogy chart that was actually done on old butcher paper from a grocery store that another great grandparent had owned. All the names you mentioned I am almost positive are on the chart. I am in the process of moving, and have that boxed up. Drop me a e-mail and I will look for it. Great hearing from you!
