Turtle Hermit's family?

[DarrienEmerald]

Obviously, we know Roshi & Baba are related. However, during the 21st tournament, in the match between Goku and "Jackie Chun," we see Roshi pull out a family chart that "proves" Jackie isn't Roshi. Obviously, that's a fabrication, but the part that interests me is the line coming down from Roshi's head to what I can only assume is s'posed to be an offspring? When the camera angle changes in the following scene and you see the chart from the side, you can clearly see another head's outline on the bottom of the page beneath Roshi's. My first guess is to just assume the whole chart is a complete fabrication (obviously, considering when it appeared in the show, it doesn't show Baba at all, since she didn't exist yet, but in retrospect ignoring that fact does lead credence to it being an outright fabrication), but is there ever any possible mention in any book, ad, whatever about Roshi having a child at any point in his lifetime?

No. Roshi had no kids.

I haven't heard anything about Kame-Sen'nin having any children.
