Ofc Mohammed is the most common name but thats a name common within the muslim community. I have noticed the name Sarah in every country, regardless of race or religion. Or it might be an abrahamic religion thing but thats most of the world atleast.
I suspect other Abrahamic names might make the cut.
Or even common names in both India and China if there’s one
and then try to find one there that is somewhat common in the US too… good luck.
