My surname is Yalla. We live in India. Is the origin of this name Hebrew or Arabic? What would my origins be?
It is difficult to know the origins of a person based only on his family name. The name has roots in Arabic, more than in Hebrew, but it also has a Hebrew connotation. The general meaning, in both Hebrew and (I believe) Arabic, is going up or forwards.
I would recommend doing some research of your family lineage, and determining your background by this method.
