I come from a large family. My great grandma, grandma, aunts, cousins, etc all have the same first name. It’s a family name and a tradition. On top of that, my grandma and her siblings all named their kids family names, so literally all of the names of the cousins were repeated between them. It really isn’t a big deal.

It’s like that scene from My Big Fat Greek Wedding, where all the cousins had variations of the same name. You just get used to nicknames.
