Senju name comes from them having skills in all areas of jutsu, we've known that for ages. This means nothing. We don't know anything of the roughly 900 year period between Hashirama and Ashura. Considering the massive changes that happened to the world in the century or so that the Villages exist, the Senju could've been a clan of wood-release spamming ninja until Hashirama. And we wouldn't know.
