Joseph Turpin (Solomon, Solomon, William) resided in Sussex County, Delaware, where he died in 1785. He married, June 18, 1772, Rachael Baynard, a daughter of Thomas and Elisabeth Baynard of Kent County, Delaware.
To his son Solomon he devised the plantation of 400 acres that had belonged to his father, Solomon Turpin, deceased, and also land called Mill Lott. To son Thomas Baynard Turpin he willed land in Caroline County called "Chance", "Mt. Holly", and "Turpin's Discovery", while his son was also to receive the dwelling plantation. Land called "Meadows" was given to his daughter Peggy. The executors named were Henry Baynard, Thomas Baynard, and John Baynard. No wife was named in the will, which is conclusive proof that she predeceased him.
