I am so happy to hear from you. I have a lot of information about the Carradines. Your grandmother was: Virginia Iola Carradine1920 - 1998,her parents were: Walker Clinton Carradine and Myrtle Flora Gordon, his parents were: Eugene Parker Carradine and Addie R. Prestinge, his parents were: James Glass Carradine and Anna Olena Vardiman.
My ancestor was Eugene Parker's brother, William Robert Carradine.
One of my current projects is to identify every descendant of James Glass. He was born in Mississippi, and came to Texas in the 1870's. I have a little information about Virginia's children, but practically nothing about their spouses or children. I would very much appreciate some help in that area.
I will be happy to share whatever I know about the Carradines. There are a lot of records in MS, and before that, SC and MD.
