Baty
A surname with several possible roots, most likely from a medieval personal name or a nickname form related to Bate/Betty-type names.
The #9,587 most common surname in the United States (2010 Census) — about 1 in every 91,049 Americans shares it.
Etymology
Baty is usually treated as a short medieval surname form connected with the old personal-name group Bate/Batty/Beattie, which itself may come from a pet form of Bartholomew or from another baptized name used as a nickname base. In some records it appears among Border surnames and spelling variants, showing that the name was fluid and often written in several ways. Older writers also connected some examples with Norman or Anglo-French forms, but the exact source is not certain for every family line.
History
The name is recorded in medieval and later English sources in many spellings, including Baty, Batye, Batty, and Batie. Bardsley notes it among Border surname forms, and Guppy records Baty/Batey in Durham and Northumberland, suggesting a northern English concentration in some families. Because the spelling was unstable, modern Baty lines may have unrelated origins that converged on the same written form.
