Ali Rıza Efendi's father, Ataturk's grandfather Hafız Ahmed Efendi's family has origins from Konya (mid anatolia) and Aydın(west anatolia). Their family records can be found in ottoman archives linked to people emigrated rumeli-Balkans. Hegira calendar 1051(1641) account 469 and hegira calendar 950(1543) account number 82... Also his father is a Hafız, means who memorized the whole koran. shows it is not so possible to say "ali rıza efendi was a jew". And at final I'd like to add that telling "ataturk has changed arabic alphabet to latin and worked against islam bla bla" can't be any proof. pls think twice before making juvenile comments.
