My name is Alyssa Behr we are 2nd cousins. I believe your mom Virginia Frances PETRI Wernli and my mom Nancy E Petri Holland were 1st cousins. We last corresponded through ancestry.com about a year and a half ago. Have you found anything else on the Petri family in Germany.
My e-mail is email@example.com
if you would like to exchange information. And if you would like some old Petri and Thompson photos, I have quite a few.
