Benjamin Snelling, born 22 Dec 1733, was a son of Aquilla Snelling and wife (2) Margaret Allen, who married in early July 1730 at Christ Church, Middlesex County, Virginia. Margaret was a daughter of Erasmus Allen and Dinah Waggoner. Benjamin died in June 1774, Hamilton Parish, Fauquier County, Virginia, and his will refers to his wife Elizabeth [Page], son Benjamin, and (much to our chagrin) "other children."
Aquilla Snelling had married (1) Mary Goar in November 1714 at the same church. By her he had son Aquilla Snelling on 28 Jun 1723.
In 1766 John Snelling, planter, and his wife Elizabeth Rose sold to his brother Benjamin Snelling, planter, 116 acres of land that had been purchased by their father, Aquilla. John died in the Revolution in November 1776 and in 1781 his wife, Elizabeth, was granted 800 pounds per year subsistence by Shenendoah County for her and her three children. I don't see a birth date for John at the moment, but it was later in the 1730s than Benjamin; 1737 comes to mind.
Hugh Snelling, born near the same time as John and Benjamin and in Fauquier County at the same time as they were, had business and legal dealings with John, but the relationship between them was not revealed. He may be another, unrecognized brother, but no one (so far as I know) has been able to positively identify him.
Aquilla Snelling, Benjamin's father, was a son of Alexander Snelling and Elizabeth (Ivison?). Alexander died about 1702. He, in turn, was a son of William Snelling, who was granted land in Gloucester County, Virginia, on 11 October 1659. He deeded that land to Alexander in 1679 and died about 1681.
There are a few more mentions of these Snellings in county and church records, but nothing I have seen gives any more genealogical information.
