Aquilla Oxley was my husband's gr. grandfather. I was very interested that he was guardian for Reuben Miller's children. Later August Holley became guardian for Aquilla's children. Have you read the Cobb book. Nicholas Cobb Descendants, Neighbors and Relatives, 1613-1983. There are a few references to Millers and lots of Cobbs. Extensive information on Bertie County. Let me know if I can look up something for you, if you do not have the book.
