Seeley
An English surname from a word meaning “happy,” “blessed,” or later “simple/innocent.”
The #3,264 most common surname in the United States (2010 Census) — about 1 in every 27,913 Americans shares it.
Etymology
Seeley is generally traced to Middle English seely or seely, a word meaning happy, blessed, harmless, or simple. Older writers connected it with Old English sǣlig, meaning blessed or prosperous, which is the usual explanation behind the surname. In some later usage the word shifted toward “simple” or “innocent,” and the surname likely began as a nickname for a mild, pious, or guileless person.
History
The name is recorded in medieval English forms such as Sely and Seely, and it has long been established in England, especially in southern and western areas. Nineteenth-century surname writers sometimes treated Sealey, Sealy, and related forms as variants or local spellings of the same name. The surname also occurs in forms influenced by regional pronunciation, and some instances may overlap with other surnames that look similar.

Fun fact
The old English adjective behind Seeley is the same broad word-family that eventually helped produce modern “silly,” whose meaning shifted dramatically over time.
