Erm .. i may have misinterpreted the whole parentage thing because i'm a little weak in my English.
But how about Kakashi?
He is well , a genius. And even before he got the Sharingan he was already well known for being a prodigy. He was kinda from the Hatake Clan and his Dad was known to be stronger and more respected than the 3 Sanins. Just that after his dad took his own life his clan kinda died down in name.. And he doesn't really have any bloodline limit in his family so yeah. Family of geniuses ?
