Hi Bill, or should I say cousin? :)
The book copies I have for Thomas Ewer are actually from "Genealogical Notes of Barnstable Families", aka the "Amos Otis Papers". The chapter on the Ewer clan begins on pg 360. If you can't locate it I would be happy to scan it and email it to you if that would help, although there are several pages to download. Email me back if you like at Niki7mg@aol.com. Good luck
Niki
