I’ve also heard him referred to as “The Nazarene” As in jesus of Nazareth.
Correct, He was born in Bethlehem, during the census but raised in Nazareth (can anything good come from Nazareth) but began His ministry in Galilee, as He was rejected from Nazareth and His own knew Him not!
It might have been Nasserine. This was a sect of Jews.
