Once again we are cousins :)
I have JUST finished researching George Allen of Sandwich trying to ascertain if his son Ralph was MY Ralph Allen. Turns out he isn't, but I have tons of information on George and his family. I will post some of it as soon as I have a chance. I can tell you that George arrived in Plymouth with his wife, three sons and a servant in 1635 with Rev. Hull's group of anabaptists. Several of his sons preceded him, along with MY Ralph Allen, who does have a family connection but I don't know what it is, except that it is not that of George's son.
However, he was made an administrator of George's will, even though he did not appear in it, and he is found among the Allen siblings getting fined and arrested for their Quaker leanings. If you have any other information that might help here, I'd love to see it.
