There are no marriage records per se that I have found. However, one can reconstruct some of their marriages from other records.
Children of Francis: John married a woman named Mary who married (2) James Mills. Elizabeth married (1)John Neale and (2) Philip Noland. Sarah married a Noland. Francis Jr. married the widow of Samuel Demoville, whose maiden name was most likely Neale. Richard and George died unmarried. Henry and Samuel removed to South Carolina. Names of spouses unknown, however there is some circumstantial evidence that they may have been part of the Jett family. The only confirmed marriage I have run across regarding the children of Thomas Awbrey was one Mary Mobley, daughter of Samuel Mobley, whose will indicates that she had married an Awbrey. This Samuel Mobley also stated in 1769 that he would serve Thomas Awbrey's sentence in debtor's prison if it came to that. Fortunately, it didn't. This doesn't help much, but these are the only marriages that I can say are one hundred percent accurate.
