Is his name not Gerald?
His name is pronounced Geordo in japanese but isnt that because Geordo is how you say Gerald in japanese?
For example I went to a maid cafe in Tokyo once, when I asked them how they pronounce my name they said it was spelled as "Deibbito" (my name is David)
So while japanese will say Deibbito it actually means David
Then again, there is another case in the Steins Gate series where the main female character is named Kurisu.
However its another case of Japanese pronunciation and that her name is actually Chris.
So while her name in english is actually Chris I refuse to call her anything but Kurisu cause Chris sounds lame af
What im saying is I was too hasty in busting your balls and Geordo is acceptable so sorry about questioning your translation skills
(Though in this case I personally prefer Gerald, likely cause that was my first exposure to the name)
