Bay
A surname that can point either to a place-name near a bay or bay-tree, or to a nickname for someone with a bay-colored complexion.
The #5,477 most common surname in the United States (2010 Census) — about 1 in every 48,621 Americans shares it.
Etymology
The surname Bay has more than one possible origin. In English records it can be local, referring to someone who lived by a bay-tree or, in some cases, by a bay or inlet; it can also be a nickname for a person described as bay-coloured, meaning reddish-brown or swarthy in complexion. The sources also suggest occasional confusion with other surnames or place-names, so not every modern bearer will share the same derivation.
History
Medieval spellings appear in English records as le Bay and ate Bey, showing both nickname and locative uses. Because the form is very short and common as a place-term, it may have developed independently in more than one family line. Later surname dictionaries treat it as a rare English name, with some possible overlap with other surnames such as Bayard or names tied to similar-sounding places.

Fun fact
In medieval surname forms, the little word le could mark a nickname, so le Bay could literally mean “the bay-colored one.”
