Usually a nickname from Edward, though some early English forms may also reflect a pet form of Edith or Edie.
The #1,858 most common surname in the United States (2010 Census) — about 1 in every 15,980 Americans shares it.
Etymology
The surname Eddy is generally explained as a pet or nickname form of Edward. In older English naming, short forms like Ed, Edde, and Edie could be used familiarly and then become hereditary surnames. Some 19th-century writers also connected Eddy with feminine pet forms such as Edith or Edie, so the name may have more than one early source in English records.
History

The name appears in English directories and records in several spelling variants, including Eddy, Eady, Eadie, and Eddis. It also traveled to North America, where it remains established but not especially common.
