Wait, you said that shade was probably Urbosa’s great great something grandfather. If that’s true, then wouldn’t that mean wars ans Sablya got back together and had another child? And he or she became the heir to the gerudo throne? That would mean that wild is like, Urbosa’s uncle or something ( I don’t know how genetics works)
Yes, but no
See, Shade and Twilight are both ancestors of the Gerudo royal family (Twi being the only male part-Gerudo in his time and all) but Twilight has many daughters. So while yes, in TTTB, one of them did marry Hyrule's kid and have Sablya, there are several others who went on to go and have their own families. His eldest daughter probably became the chief after him, so Urbosa would be descended from her, not Warriors and Sablya.
(Although the idea of Warriors finding out he's the father to the next line of Gerudo rulers would have been HILARIOUS!)
So, I guess Urbosa would be more like Wild's cousin?
