My paternal grandmother has the surname Behyat and lives in Tehran , Iran. Her father (my great grandfather) died some time in the 1950s or 1960s, I believe, and apparently he had some German and Arab background but I think nobody knows this for sure. His name was Alexander/Iskandar. I know there are some family of mine in the USA who are related to the Behyat family.
If anybody knows anything about my great grandfather, Alexander/Iskandar Behyat, please reply. I did a DNA test on here and there were some "new" ethnicities I didn't know I had, such as from the Iberian Peninsula, Italy/Greece, Asia South and there was Europe West but only 1%. So it is very possible that he could have had some European background.
