Thanks for getting back with me on that.I am still just confused.I am not convinced one way or the other.I believe Abigail's birth date could have been wrong, and even the marriage date with Ebenezer could be wrong.The way that Ebenezer and Abigail named their children strongly fits with Zebulon's children's names: Mary, Philip, Sara, and Zebulon. However, the name Philip is also an Allen name.
I found something interesting about Zebulon.It seems that he accused a woman named Joan Peney of witchcraft in 1692 for afflicting his daughter Mary Hill.You can go here: http://etext.virginia.edu/salem/witchcraft/archives/BPL/http://etext.virginia.edu/salem/witchcraft/archives/BPL/ and check out the original warrant for arrest, and the complaint that Zebulon made.
I also read somewhere that Zebulon moved from Glouchester to Salem in 1657. We know they were in Saybrook in 1662, and they were back in Salem at least by 1684. Salem's not that far away from Dartmouth, they could have met Ebenezer or his family through travels or something when they lived there the first time.I don't know.
If you learn anything new, I would appreciate you letting me know.
