I have wondered in the past if there is a connection between the Provençal (and later Piedmontese) Cassin family and that of Aleppo. Now it seems that according to some it's the same family:"Sarina traced the Kassin family starting in 1384. It was founded in Charleville, France and they were in the winemaking and jewelry making industries. France expelled the Jews at the end of the 12th century- early 13th century and many moved to northern Spain and became Sephardim. Sarina showed a family tree starting with Shelomo Kassin born in 1465 in Segovia. The tree shows how one of the descendants arrives in Aleppo (Syria) in 1540. The mystery was where was Shelomo until 1540? Sarina also showed documents proving some of the Kassin’s remained in Spain in 1600’s."Is this verified?
