I wanted to mention masons or woodsman or some kind of lodge fraternity. I know our Danzig ancestor was suppose to have been a Mason there before he came. Not well received there either. I say this with out having seen any kind of pins etc.

Policeman or pilot or bus driver?

I wanted to see what his occupation was when he came to Pennsylvania wasn’t it. Coal miner or factory. I am not sure about the time frame for unions.
My grandfather worked coal mine in Illn around 1900. He had to be a union. Lately, I think I may have found a tie tack kind of jewlry that might have had something to do with mining. Maybe part of the union piece or a gift from someone. Unfortunately the picture we had faded from improper care. And his helmets and other things burnt in a house fire. So eagerly I will check to see if it is our only souvenir of his days as a miner. The wages went towards his farm purchase.

I was thinking maybe some kind of union… or group.
Something about the shape of it is in the back of my mind.
I am wishing you the best luck for your search.
just me here.
