Etymology
Kaylor is usually treated as an English surname formed from an occupational byname, probably connected with Middle English words for a key or key-bearer, or with a related nickname/agent form built on that idea. In many cases, surnames like this began as labels for a person who made, carried, or was entrusted with keys. The exact pathway is not certain, and Kaylor may also reflect regional spelling variation of similar-sounding surnames.
History
The name is found in the English-speaking world and is especially familiar in the United States, where later spelling stabilization produced several variant forms. Like many surnames of this type, it likely arose independently in more than one place from a descriptive or occupational nickname. Modern American bearers may descend from different original families that converged on the same spelling.
