Almost all of these family names have Somerset County connections, and were Amish or Mennonite prior to being Brethren. May I ask how one can tell if the surname is Amish, Mennonite or Brethren? I was able to go back another 4 generations on one of my main lines and have come to NEWCOMER, which I have been led to believe is Swiss and Mennonite. How can someone tell this by the surname. Many Blessings, Janet
