Bryan, thanks for your informative reply. I'll try to get in touch with you the next time I am in Richmond. Thanks, too, for your ancestral lineage back to Col. Thomas Pettus. You asked about John Dabney Pettus. That name is a compromise of sorts between genealogists who claimed that Ann Overton married Dabney Pettus and those who claimed that she married John Pettus. Actually, neither of these conjectures, to my knowledge (and I have been at this for 37 years), is based upon any written records from the period. Rather, it all goes back to the recollections of a nineteenth-century genealogist who recalled things she had heard as a child from someone who married into the Pettus family. One of those things was the marriage of Ann Overton to Dabney Pettus. That marriage would have had to occur in the late 17th C., but no Ann Overton or Dabney Pettus is on record until the next generation. On the other hand, a family bible record does mention a "John Pettus and his wife Ann" whose son Thomas was born in 1712. Thomas gave some of his children the name Overton, which suggests (but doesn't prove) that his mother was an Overton. I have a more complete discussion of this problem in my forthcoming book.
There were indeed descendants of James Bray and his wife, Mourning, widow of Thomas Pettus II. I have not personally done much on Bray genealogy, but I did see a report on the subject at the Rockefellar Library in Williamsburg. The report covers several generations to the mid-19th C., as I recall.
Thomas Pettus of Lunenburg, son of John and Ann Pettus, mentioned above, married Amey Walker, daughter of David Walker and his wife, Mary Munford, in 1735. Thomas was my fifth great-grandfather. Ann Pettus who married Joseph Eggleston, was the sister of John Pettus of Louisa County (not to be confused with the earlier John Pettus). John also had children with the Overton name. Presumably, John and Thomas were brothers, but, again, this is difficult to prove for lack of early records. If so, Thomas and Ann Pettus were siblings. There is convincing circumstantial evidence that Thomas and John were brothers. For example, both men had children with the name Overton. Also, John's daughter, Barbara Overton Pettus, married Thomas's grandson, Thomas Pettus of Charlotte County (the marriage is on record).
Pekay's grandmother, Bertha, was my dad's mother's sister.
Another problem that early genealogists argued over is whether Col. Thomas Pettus was the son or the brother of William Pettus of Norwich, England. William married Mary Gleane, mentioned in your message. Actually, William and Thomas were brothers, as proven by extant records in England that apparently were overlooked by early genealogists. My book reviews the evidence that proves the relationship.
I neglected to identify the father of John Pettus, father of Thomas, mentioned above. That, too, is a highly controversial topic, due to the loss of early records, but my book has an extensive treatment of the problem based on evidence not previously reported. I will be glad to discuss it with you when we meet.
