I left the State Archives in Raleigh, NC today with some great new information on the Venters family. I may have found a possible tie for this Nancy written above, too.
First, I found a record at the State Archives for "Arthur Ventress" dated 1772 in the Individual Accounts of Bertie County, North Carolina. It is a full page list of merchandise purchased by Arthur Venters from a man named Michael Payne. The interesting thing about this list is: 1) It makes a definite tie back to Bertie County for Arthur Venters (which is known to have been the location of the birth of Mary Robinson, as well as that of Abraham Perry and of Arnold R. Perry), 2) Michael Payne was listed as being in Hertford County, NC, and somehow this Individual Account of Arthur Venters was put into the Bertie County file (this occurred at the same point in time that Hertford County was carved out of Bertie. Since Hertford's records burned, it is quite possible that Arthur Venters lived in the section of Bertie that became Hertford, with the records lost), and 3) Malachi Venters also had a full page list of merchandise purchased from Michael Payne of Hertford County that was filed along with Arthur Venters' merchandise list. The descendants of Malachi Venters sold a Land Grant given to Malachi Venters for his service in the Revolutionary War to William Walton of Hertford County, North Carolina (the grant says that Malachi Venters was of Pasquotank County, so perhaps Pasquotank County should also be reviewed for traces of Arthur Venters between 1772 and the time he received his land in Onslow County around 1780).
It is important to note that a Daniel and Patience Venters lived in Bertie County at this time, and were elderly. It is possible that Arthur Venters was moving out of Bertie County at about this time of 1772, but that the merchandise note was filed in his old home county of Bertie. This gives additional chance for the meeting between Mary Robinson and Arthur Venters.
Incidentally, I have resolved who Mary Robinson's parents were. Mary was born in the mid 1750s to George Robinson and Ann Fleetwood Robinson of Bertie County. George Robinson died in 1759, and Ann Fleetwood Robinson remarried to John Cook around 1761. I found George Robinson's Estate settlement papers at Raleigh this weekend, and they show the division in a nice neat table that was prepared by John Cook -- Administrator of George Robinson's estate.
I also have resolved the birth of another child to Abraham Perry. Abraham Perry was the father (illegitimate) of a girl named Nancy, who was born around 1773 to a girl named Elizabeth Hollum of Bertie County. According to the court records, Abraham was brought before a magistrate to answer to Elizabeth Hollum's claims that Abraham Perry was the father of her child. The records also indicate that Abraham attempted to provide for the child. The records show that this Nancy was born around 1773. It is odd that Elizabeth "Betsy" Perry is never recorded in any of the Bertie County records, yet Arnold is recorded as well as his sister Ascenath "Sena". Perhaps Elizabeth Hollum's daughter, Nancy, became Nancy Perry (after her father, Abraham Perry), and that Nancy in turn had Elizabeth "Betsy" Perry? Just guessing at present, but it is worth sounding off. Regardless, it is indeed interesting to note that Abraham Perry fathered illegitimate children by more than one woman.
Another item of interest is the fact that Arnold R. Perry was known in Bertie County from the time of his birth on December 10th, 1784 as "Arlan Perry Roberson", and was indentured to Sparkman Stone of Bertie County until he turned 21 on December 10th, 1805. Less than one month after completing his Indenture to Sparkman Stone, on January 6th, 1806, Arlan had switched his name around to "Arnal R. Perry", and was appointing his step father, Arthur Venters, as his Power of Attorney in Onslow County, NC, prior to heading off to Floyd County, Kentucky. Arnold's sister, Senath Roberson, married to John Hill of Bertie County, North Carolina and remained behind in Bertie County. John Hill is listed on the 1820 Census of Bertie County, but does not show up on following records.
