I'm working with a second cousin who lives in Israel determining the origin of what morphed into Berazanoff in the UK. Our original thought for a very concrete reason was Spain, but my cousin was told that Berezano is / was a common last name for both Jewish and non-Jewish Kurdistani's. Our GGfather apparently originated >from Tbilisi, Georgia but I don't know if that was him or prior generations who made the move to the Ukraine, where he married our GGM. In addition my first cousin's (we are daughters of sisters) son had his mitochondrial DNA tested and it indicated early roots in the Caucasus.
