How did Hashirama know?

[GodaimeRaikage]

People are very ignorant the senju and uchiha share the same common ancestor its most likely information was passed through the senju/uzumaki clan. just how the tablet was passed for the uchiha

Senju Clan, yes.Uzumaki no.People really need to stop placing the uzumaki clan into everything Senju.The uzumaki clan aren't direct descendants of the sage or the sage's two son.The Uzumakus are a distance relative clan of the senju.

Uzumaki clan are distant relatives of the senju correct, but i put Uzumaki in their beccause they still have information just like the senju.... sharing intell with both clans
