My name is Lisa Deckter. I believe I may have some answers for you about the Decker (part of my family doesn't have the t in their last name as we do). I was researching the Decker/Deckter family when I ran across you post entitled "Gach Futterman".
The of names and places you listed are familiar to me. Abe, Bessie, Decker, Michigan then California. And actually before Michigan they were in Philadelphia were the majority of my family remains. And we are Jewish.
How about of you email me, as there is names, and relationship, places info, etc.
