Ayers
An English surname that may come from the name Ayer/Ayr, often linked to a place-name or an earlier personal name.
The #875 most common surname in the United States (2010 Census) — about 1 in every 7,792 Americans shares it.
Etymology
The surname Ayers is usually treated as a variant of Ayer or Ayr, and in older surname books it is often connected with a place-name such as Ayr in Scotland or with similar names in England and on the Continent. In some cases it may also reflect an older personal name rather than a direct place of origin, so the form is not always easy to separate cleanly from Ayer, Ayre, and Ayrs. The ending -s can be a patronymic or possessive-style addition, giving a sense of "belonging to" or "descended from" Ayer/Ayr.
History
Historical surname dictionaries group Ayers with Ayer, Ayre, and Ayr, showing that the spelling has long floated among several closely related forms. The name appears in British records by the early modern period, and later spread widely in English-speaking countries, especially through migration to North America. Because the sources disagree on whether the base is locational or personal-name based, the surname is best treated as having a mixed or uncertain origin.

Fun fact
19th-century surname writers often filed Ayers right next to Ayre and Ayr, which is a clue that spelling variation was common and the family name was not yet standardized.
