I'm also curious about why there's only 1 single name given, for him. But in his main article, there's written "Oshō (和尚, Bonze)". As I understand it, his real name is Bonze, and it's been changed to Oshô in the English translation.

But still, it's an interesting point. Maybe he really is a Shiba, and his surname isn't revealed yet to keep it a secret for now. And if it's true, he might be the head of the main branch of the clan, as Isshin appeared to be the head of the clan, but from a different branch, while he was the captain of Squad 10.
