Caine
A surname with several possible roots, including a Manx/Irish form and a possible place-name origin.
The #7,647 most common surname in the United States (2010 Census) — about 1 in every 71,090 Americans shares it.
Etymology
The surname Caine has been explained in more than one way. Older dictionaries connect it with the Manx and Gaelic word for “beloved,” and also point to Manx families bearing the name early. Other etymologies link it to French place-names such as Cahaignes in Normandy, or to the Irish surname O’Cathain. Because these explanations differ and may reflect separate families, the name is best treated as having multiple possible origins.
History
Bardsley notes early spellings such as Caine and Cayne and associates the name with Manx descent in well-known bearers like Hall Caine. Lower also cross-references it from Cane and gives a Gaelic sense of “beloved.” Barber adds alternative derivations from a Norman place-name and from Irish O’Cathain, showing that the surname likely arose independently in more than one place and family line.
