I know I have relatives in Fassuta. My grandfather Mtanes Kessis came from there to Argentina circa 1910. He became "Antonio Jorge", his name in Spanish.
I guess the name "Antonio" is translation of Mtanes, and the surname "Jorge" is translation of Yiries.
He had three children, one of them, the only male, was my father. And I have three sons myself. So, as of today, there are three grandgrandsons with Mtanes' surname in Argentina (which is "Jorge", but should be Kessis).
