It's not only linguistic drift, it's about awareness. Three used to be a beer narrow set of names (in western Europe) that got used, with a mostly Catholic base, so your John, Paul, Marie type names which would hear the variation of your country. Usually the ancestors would be reflected in the naming convention.

However awareness spreads through media like newspaper and film. Celebrity means that different spellings of names get noticed and get used, regardless of culture. There's Estonian men named James, because of James Dean (or Bond). There's kids named after fashion brands nowadays.

The boundary between appropriation and homage is thin. Is Willem Dafoes embracing his school nickname insensitive towards the Dutch? It can be cringey, like Shia Labeoufs mother making two spelling mistakes in her new french inspired last name. It's a bit time deaf maybe but I wouldn't personally classify it as inappropriate.

Ultimately culture works by drawing inspiration from others. Like Picasso being inspired by Cycladic sculpture and Renaissance artist by roman art.
