Hello Phil, It is good to hear from you again. My source for this information is Alva Floyd who is a great-grandson of Basil Floyd. He told me that Francis Floyd (died 1816) and his wife Susanna and their daughter-in-law,the wife of John Floyd, are buried near High Rock Lake in Davidson Co. NC. My wife and I did not visit their graves. Alva said that there is just a rock marking their graves. I have a distant cousin William Floyd who also gaveme the same information. He does not know what happen to John Floyd the father of the twins Francis and Basil.
