Yes, they are just two different ways of romanising the Greek name¨Γεώργιος". "Georgios" is a graphemic transliteration (more etymological and faithful to the Greek spelling) in that the Greek letter gamma (γ) usually corresponds to an English 'g', whereas "Yeoryios" is a phonetic transcription (more faithful to the actual Greek pronunciation), since the letter gamma is pronounced like an English y when it comes before certain letters, such as epsilon (ε) and iota (ι). http://en.wikipedia.org/wiki/Romanization_of_Greek
