Haha, my point was, Jiraiya wasn't known as the White Fang, rather as one of the Sannin. In the Flashbacks, we don't see him using a chakra blade, which we do see Kakashi use, who inherited it from his father.

And didn't Kakashi initially suspect Jiraiya to be one of the Sannin when they first met? If Jiraiya was his father, Kakashi would have known who he was, and not ask Jiraiya to help the Third. I'm not too sure which episode it was, but I do recall their first conversation.
And Kakashi said his father committed suicide. I doubt that he'd make up that story.
