<p>As revealed in Chapter 646, the surname from Rikudo Sennin (Sage of the Six Paths) is "Oosutsuki." </p>

<p>Why do his two sons have different surnames (Uchiha and Senju), instead of inheriting their father's surname?</p>

I think it is because the two sons couldn't get along. And then they didn't want to share the same surname, so they both changed. This is just a guess though.

I don't think his sons were named Uchiha and Senjuu. The Uchiha and Senjuu are *descendants* from his sons. But I may be wrong

This question *might be* opinion-based or speculations for now.

My speculation is on the same line as JNat, I don't remember them being called by names anywhere but only that they were the starting point of two clans, Also I do believe its normal place for the surname to change over generations say when one clan mingles with another and the subsequent generation might even adopt the mother's/father's clan surname or have their own new name for clan as a surname to show the uniqueness... best example that I know where surname does not have to follow from the ancestor is with a Harry Potter reference Marvolo Gaunt -> Salzar Slytherin -> Tom Marvolo *Riddle*
