Hal:
Thanks for answering me, and for giving me another reference! It's appreciated very much. I will check with Samuel Etris.
However, I am curious. You mentioned you had no such Etris from any period other than the late 1700's. Do you have a George L. Etris/Ettress/Etress from the late 1700's? It is possible that it wasn't a cousin as my Mother believed, but the name of one of his sisters in-laws or his Mother's relatives. If it isn't too much trouble, I would really appreciate knowing. I'm sort of getting over being surprised when it comes to my grandfather!
Thanks again,
Pat
