Surname Overview
Surname Candidate Confirmation
The source includes 础 in a Chinese Baijiaxing surname lookup and calls it the “础 surname.” It gives the reading chǔ and the traditional form 礎. This establishes only that the website treats it as a Chinese-character surname entry, not any ethnic affiliation.

Research Notes
Evidence Limit
The source explicitly states that information on the 础 surname has not yet been collected. The supplied text therefore does not support claims about its origins, documentary attestations, commanderies or halls, migration and distribution, historical people, or genealogical generation names.
