Most of my Ancestors came from Mecklenburg and Brunswick Counties in Virginia. My research has just shown that they were connected by familial and personal lines in that area and came together to this local, or came later, as they already had family in the area, much as people do today when they relocate, unless it is for a job. One member of a family hears of good bottom land, or an opportunity in another area, the grass is greener, etc. And several of them relocate together, or...others arrive after the first ones already are settled in. Then, they remain bound by area, religion and family ties and intermarry, so many of the same people are in the family trees of the modern citizens of this area.
