I don't know if I will be of any help to you. I have traced my Porters (specifically Charles Porter) back to Isle of Wight, Va. Charles, b ca 1680, d. 1734. This Chs. had a son named Thomas (b. ca 1715)....he had a son Thomas (b ca 1738), and he had a son Thomas (I have no birthdate). Thomas #2's wife, named in will, was "Julan." My info stops with the last Thomas. This may not be your line, but interesting that there were all these Porters in Isle of Wight at that time. I bet there's a connection.
