Hello Barb,
Based on DNA, we know that Casper Starr of Virginia and Rowan Co., NC is related to the Guilford Co., NC brothers (Adam, John and Jacob Starr).
We have theorized that (based on age and near associations) that Casper might be the uncle of the Guilford Co., NC brothers. However, we do not have paper proof as of yet.
We don't have a paper trail that proves that Jacob Starr of Lincoln Co., NC is the same as the Guilford Co., NC fellow of the same name. We can't prove that he isn't, either. We have not gotten a DNA test from a man that descends from Jacob yet, which should prove or disprove this theory.
cheers,
Vicki
