Dear Dan, Robert and other William Calvert descendants, I reviewed the letters Dan sent and conclude that one family has surmised a relationship based on the fact that William (1783) named one of his daughters Cynthia Crupper Calvert. That would point to either George or Jacob who both married Crupper girls. The Deatherage cousins could work for either family. Remember William Deatherage was a step-son of George Calvert. Look at two other points. a) O'Gorman allows for more issue from Jacob and Sarah (pg 75 - perhaps others) b) We have established that our William's brother John died by 1782 in Tennessee (Washington County, TN Court of Pleas and Quarter Sessions 1782) O'Gorman says George's son John died in 1790 in Culpepper Co., VA. I think Jacob Calvert is a better target the George. We need (as Dan said) primary evidence that Cynthia Calvert's middle name is Crupper. I will look into land records in Prince William Co., VA to see if we can reconstruct the probate of Jacob's estate (the will book is missing) Let me know what you think. Paul Bardell
