Reply To: Are sfardim from the 10 shvatim

I have a Persian friend who can trace himself to Shevet Shimon. He claims many Yazdis can do the same (trace themselves to a shevet not from Yehuda. He also says many Bucharians can do the same.
The pasuk clearly says the Aseres Hashvatim were exiled to Madai, which is Iran. It makes sense that when the Yiddin came to Madai during the Megillah, they reintegrated.
