Turkish, Arab, and Bosnian in one family is a real pattern, not a rare footnote. People moved through the Balkans in the 1910s during those wars, so that arrival window lines up. Sorry about your grandma. Fifty days is still close. The part worth answering is the question: who here has Turkish, Jewish, Iranian, or Arab family with a known European or Balkan branch, and which town or decade shows up?
