I was scrolling through the List of Latinised Names for a lark and some of these you wouldn't belive:
Alexander Agricola was born Alexander Ackerman
Hieronymus Bosch was born Jheronimus (Jeroen) van Aken
Confucius was born Kong Fuzi
Nicolaus Copernicus was born Niklas Koppernigk
Desiderius Erasmus was born Gerrit Gerritszoon
Georgius Macropedius was born Joris van Lanckvelt
Gerardus Mercator was born Geert de Kremer
Paracelcus was born Philip von Hohenheim
Some of these are clearly professions translated to Latin (Kremer, Ackerman) and others simply substitute each syllable with the closest Latin equivalent (Kong Fuzi, Koppernigk) and add -us. Then the boldest ones simply invent a name entirely unrelated to their birth name, and honestly, I respect the hustle. I would also be inclined to change my name if I was named Gerrit Gerritszoon, but I don't think I would have the balls to pull off calling myself Desiderius Erasmus, which is not only an insane glow-up but a xianxia-protagonist-level name in its own right. He's literally called "the desired one" in both his first and last names! And we still know his name today, so he went and lived up to it. Name someone who did it better than him.
