Thank you so much for such detailed information. I have another source which you may wish to look up by the same author you referenced in your post. It is "First Settlers of Ye Plantations of Piscataway and Woodsridge Olde East New Jersey", by Orra Eugene Monnette, Leroy Carman Press, California, 1931 Call Number F144.P68M74.pt.3. This book contains the history of the two towns in old east New Jersey. It is available on genealogylibrary.com, a subscription service or you may be able to order it through an interlibrary loan.
My Rachel Stelle received a marriage license on June 01, 1757 to marry Benjamin Dunn in Woodbridge, NJ according to "Documents Relating to the Colonial History of New Jersey" Vol. 22, p. 303 by William Nelson, The Press Printing and Publishing Co., NJ, 1900.
However if she is the same one to marry Ephraim Fitzrandolph on July 11, 1752 in Monmouth, NJ & he died on November 03, 1793, then there is a conflict with the two marriages unless a divorce occured.
If you find more on this family, please let me know! - Mary
