Poore
A surname usually from a nickname for someone poor or humble, though in some cases it is linked to Norman French Power/Poer forms.
The #4,315 most common surname in the United States (2010 Census) — about 1 in every 37,469 Americans shares it.
Etymology
The most direct explanation is Middle English poore, poor, from Old French paure/povre and ultimately Latin pauper, meaning "poor" or "needy." In medieval records the name appears as forms like le Poure, which fits a nickname for a poor person or someone regarded as humble. Some older surname dictionaries also note overlap with Norman French Poer/Power spellings, so not every modern Poore family necessarily has the same origin.
History
The surname is recorded in England by the late 13th century, and spellings varied widely: Poore, Poor, Poer, Powre, and Power all appear in historical material. In some lines the name became established enough to be hereditary rather than merely descriptive. Because of the spelling overlap with Power/Poer, family histories sometimes need documentary tracing rather than relying on the modern form alone.

Fun fact
A medieval byname like le Poure could begin as a description but later turn into a fixed family surname, even after the original meaning was forgotten.
