Is there any evidence that Sherpas summited Mt. Everest before Edmund Hillary and Tenzing Norgay did it in 1953?

I know Tenzing Norgay was a Sherpa; I’m just wondering if Western history conveniently glossed over prior summits to get Edmund Hillary in the record books.

Here is a similar question that addresses the spiritual beliefs of area as well as the lack of climbing gear that makes such a summit unlikely, but possible. /u/caitrona and /u/Bacarruda provided insightful answers.
