My sisters and I are planning a trip next year to research our Turkish Family History but don't know where to start or how to find the records pertaining to our Paternal Grandfather. We know that he went by the name Hokmey Ahmed in the USA, but census records show his last name as Ahmat and Ahmet. His application for a US Social Security Card, that was needed to work in the US, listed his fathers name as Mamet Ahmed and his mother as Hanom Gurse (Both of Turkey)(I believe the Social Security folks spelled it as it sounded.). His date of birth is listed as 15 March, 1886 in (Constantinople) Istanbul. He died in Turkey, according to the US Consulate in Adana, Turkey in December of 1966. We know that he was a diabetic and had lost 1 or both of his legs before his death. We believe he also spent time in Ankara when he returned to Turkey from the US around 1957. Any help you could provide would be appreciated. Thank you.
