The Keaton Surname Secret: Why Hollywood’s Most Famous Keatons Aren't Related at All
By Alexander Ross
The linguistic lineage of the Keaton surname predates Hollywood by nearly a millennium. Onomastic records trace the moniker back to an English toponymic surname, deriving primarily from ancient place names such as Keighton in Nottinghamshire or localities in Devon and Northumberland.
In Middle English and Old English records, place names ending in "-ton" (from tūn) designated an enclosure, farmstead, or fortified village. The prefix generally stemmed from personal names or geographical markers, such as kēy, denoting low-lying marshes or cows. When local inhabitants migrated from agrarian villages into surrounding market towns during the 13th and 14th centuries, tax assessors registered them by their place of origin: de Ketone or de Keton. Over centuries of oral transcription, church registers regularized the spelling into Keaton, Keyton, and Caten.
Buster Keaton's ancestry inherited this patronymic lineage directly through British settlers who landed in early North America. Diane Keaton's maternal branch carried the same historical root. The phonetic strength of the word, two sharp syllables punctuated by hard consonants, explains why a young Michael Douglas found it so striking while leafing through a phone directory in 1975.
