For one, I would not know much about the family things as I haven't read any of the books as I'm dirt poor and cannot afford to buy any of the books. Secondly, this biography was written two years ago on my roleplay site, I uploaded it for a display one, thus far, there are countless mistakes. Thirdly, I'm not quite sure about the life span, again it was made a while ago.
The 'ee is the military suffix for a Sangheili, but I don't fully understand your question, please expand a little more.
I am more informed with everything else. As I said, I haven't brought any books yet, so when I do I'll be sure to read them and then edit.
EDIT: Going back to the father thing. In Sangheili clans on Reach and 3 and such, we were very close to our bloodlines and we played with the father of the bloodline (Kaidon) regularly. I think this is were the Sangheili warriors get confused with as we spend a lot of time playing with our fathers. As for the books, I know nothing of them so I cannot be dubbed 'dumb' as I have no knowledge on them. Also, the brother thing was an actual player on Halo 3 that I played with all the time. He actually went offline and never cam back on which is why I had written it like that. It was after the Great Schism and such when he went to find him as he was captured by humans. I was like ten at this time and very, very naive so that probably accounts for bad story telling.
