Look so we can just get this out of the way, the main thing is the wiki, both of them, just state that Impa is a name of several female members of Sheikah. Doesn't actually say they are all descended from each other. Like Impaz is heavily implied to be descended from Impa but it couldn't be the same Impa from OoT because his Impa opened up the Hidden Village to outsiders aka had control over the village to do so. It does not have to be the same family line but just one of the Sheikah of the generation that happens to be named Impa. This about to overtake a whole page. lolz

Impa was the name of the Shiekah who was said to have been the first nursemaid for Princess Zelda (SS)-- helping her and the Hero of Time save the world of Hyrule. Impa from OoT never was said to have been the leader of the Shiekah, so the same shall be in the RP-- she was not/never has been the leader of the Shiekah. Impa will be the name passed down for Shiekah women destined/expected to take on the role of Zelda's nursemaid. 

Kai, For simplicity's sake, I would prefer if you just make your character the son of someone who is held in very high respect within the Shiekah tribe, as I expect we may butt heads if he's the son of the leader and/or Impa. Not a requirement-- but a strong suggestion.
