Doster
A surname most likely from a nickname or a regional spelling variant rather than a single fixed meaning.
The #7,852 most common surname in the United States (2010 Census) — about 1 in every 73,249 Americans shares it.
Etymology
Doster is an uncommon surname whose origin is not firmly established in the standard surname literature. In English-speaking records it is often treated as a variant spelling or altered form of an older surname rather than as a straightforward occupational or place-name. The first element may reflect a nickname source or a phonetic reshaping of an earlier name, but no single derivation is secure enough to state confidently.
History
The surname appears mainly in English-speaking countries, especially the United States, where it is relatively uncommon. Like many such names, it may have stabilized under one spelling only after families migrated and clerks recorded the name phonetically. Because the evidence is thin, historical links to any one locality or family line should be treated cautiously.

Fun fact
In modern U.S. records, Doster is uncommon enough that it may have multiple unrelated family lines sharing the same spelling.
