Charles Clay (passed away about 18 months ago) - also a descendent of your Charles Clay had DNA testing done. The end results were that he was a descendant of the Clay family from a female, meaning that Emily Clay was a descendant of the Clay blood. With those results it sort of through speculation of James & Lucy Clay being her in-laws and who the father of the 5 Clay brothers were, if they were all the same father. I have to remember my facts without looking back, but Lucy and Emily came to Russell County, VA around 1840. I would have to check, but if my memory is correct there was another Clay that lived either next door or a couple doors away. Not sure of the relationship but I believe this was the reason for Lucy and Emily moving to Russell County, VA from NC as there was no other family there for them.
