# 4 in your list, Philip Doddridge who m. a Powell. Would this be an Elizabeth who m. 1st a Philip Doddridge, 2nd Thomas Thorp, Jr. who d. 11/19/1689, and 3rd., at Woodbridge, NJ, 12/4/1689, Richard Powell who d. after 2/1704/05. This Richard Powell 1677/78 had bought the Woodbridge lands of Gov. Carteret. He had an earlier wife Katherine Hughes who d. 5/16/1689 at Woodbridge, NJ. This Richard Powell may have come out of a Quaker Powell family of Jamaica, LI, NY.
# 3 in your list, John Doddridge & Elizabeth Syderdam, would she perhaps be a "Suydam", and then again, the English recorders butchered the Dutch names, and vice versa, so any similar spellings could all be the same family.
Any additional data, dates, locations, so forth, on the earliest generations, would be of great help.
