I don't have documentation for this, but I read somewhere that Zebulon Shippy's father's name was Thomas Shippee JR. b. Abt. 1725 in Providence, R.I.and he was the son of Thomas Shippee Sr. b. Abt. 1700 in Providence, the son of Samuel Shippee b. Abt. 1675 in Providence, the son of David Shippee b. Abt. 1640.
At least this will give you somewhere to look. Good luck, Phyllis
