I have a character in my novel who is originally from Algeria. After researching some Arabic names I came across the name Laith (لَيْث) which I really fell in love with. However, after researching some other people with this name I find that it's used in Eastern Arabic countries such as Iran, Iraq, Palestine but I can't find any North African usage of the name. It got me thinking, are there some names that are not used beyond a certain geographical region? Would it be unusual for my character to have this name? I hope my question makes sense. A big thank you to anyone that can provide some insight.
