It was only stated that he was used to have a normal name before, not that he forgot it.

About the names, I think Mashiro (for the color and the unisexness that would suit his genderless body) and Yukio (though the kanjis are different, it has the word "snow" in its pronunciation, which gave a sense of whiteness and purity) would fit him. They are very ordinary, like Accel said. Anyway, is Shirayuki a name? I thought it was a surname.
