We've seen several other shinobi of Hashirama's era that were all considered legends in their own village but unremarkable in others. And even in the Leaf, Hashirama and Madara were the main legends despite Tobirama being a top-tier shinobi himself.

Sure, it's clear Hashirama's kid didn't achieve a similar legendary status, but they could've been quite the shinobi without becoming legendary.

Plus, it's possible his kid died after becoming a dad and before becoming truly legendary.
