Samuel of Braintree came from England.Edward came from Scotland.They left Annanias and Gershom Allen out of the New Jersey Allens, I see.They ended up in Wilkes & Surry Counties NC about the same time David and family arrived there.I've never found anything to connect them other than coming from New Jersey.
Some time ago I corresponded with a man who descends from Jonas Allen.Jonas was one of the Elizabethtown or Morristown NJ Allens.During the Revolutionary War, he evidently sided with the Tories and left New Jersey for [I believe] Nova Scotia.I know it was in Canada.I will see if I can find our correspondence and post some of the info here.I'm pretty sure he connects to David Allen Sr family - probably a cousin.
You have done a lot of good research on this Allen family.I am impressed !!While I can't prove I'm related to any of them, I feel strongly my Joseph Allen b c1778-82 NC was a close family member.He lived near Adoniram, Jr. in Buncombe and Yancey Counties NC for many years.He even had a grandson named Adoniram - a for sure "tie-in".
