As I also put it in the trivia, the name is spelled Oeagrus or Oiagros and I went with the latter because it was closer to the direct romanization. I'm 99% sure this is what the creators intended to reference given the fact that his nephew is named Orpheus. Code Geass likes to go with themes like that.

Plus u's are often silent in Japanese. The only single "letter" kana are vowels and n so for example if a loanword ends in a consonant the Japanese romanization would likely have a "u" at the end. Perfect example, Lelouch and "Ru-ruu-shi-yu" (ones that end up with an i sound next to a y it gets slurred together enough that it's romanized without the i, for example the name Kyoko which would technically be "Ki-yo-ko" hence Japanese Lelouch sounding more like "Rurushu"). And for some reason sometimes Greek has silent s. Taking both of these into account O-i-a-gu-ro becomes Oiagros.
