General Summary

These documents tell a clear story: You are Fehim CALGAV, born in Üsküdar in 1969. Since your father was a high-ranking Naval Officer (at the time serving under or associated with the Landing Fleet Command), you held a military dependent ID. During your youth, you lived in Maltepe and graduated from Maltepe High School.
As we clarified earlier, while the typewriter on the military card makes the last letter look like a “Y,” the handwritten school ID clearly confirms your surname as CALGAV.
