Welcome! I'm also new here.
...I have a similar hobby, except I look way too extensively into the roots of the names I pick. What purpose does it serve? Absolutely none! Take the name Alcide. Sounds weird right?
It's the french form of Alcides , which is itself the latinized form for Αλκειδης (Alkeides), derived from αλκη (alke) "strength, vigor" and the common patronymic suffix ιδης (ides), "son of". It was the birthname of Heracles.
