Sam: Since you didn’t answer my question I will ask it again. BTW, just out of curiosity, are you a boy or a girl?
So suddenly after 200 years they magically became kohanim again according to all poskim?
I’m sure you know the story of the gra with his pidyon haben who went around to all the people who claimed to be kohanim since they were all only safek until he met one family with a shtar.
The Yam Shel Shlomo I believe states that one reason we do not give kohen challah is because safek kohen.
I remember reading about this on a thread here not too long ago. Like I said this is not the place for this convo.
