Perhaps I have Jewish Some roots

I’m moroccan, my great grandmother migrated from a oasis town in South- Algeria called Touat. Thus the last name is Atouati. Searched it up, seeing many Jews & at least 2 rabbis had the same last name. The Jews have been in that place for a long time since antiquity I think. I’m Muslim, & will always be, hopefully.

Asking u, is this common last name or even such a situation. Is it common. Thinking if a dna test, but heard Sephardic dna is hardly detected if at all
