Register
A rare surname that likely began as a nickname or occupational name linked to a parish register or registrar.
The #3,914 most common surname in the United States (2010 Census) — about 1 in every 34,022 Americans shares it.
Etymology
The surname is usually explained from Middle English and Anglo-French words for a register or registrar, ultimately from Late Latin registrum and the verb regestum/regere meaning to record or enter in writing. In this sense, it could have been applied to someone who kept records, worked as a registrar, or was otherwise associated with official written lists. Some 19th-century writers also treated it as a corruption of Rochester in at least one local dialectal sense, so the name may have more than one historical pathway.
History
The name is uncommon and appears in English records as a surname rather than a major hereditary line. Victorian surname writers disagreed about it: Harrison connected it with registrar/register, while Lower reported a Sussex dialect form meaning a baptismal register and treated it as a corruption of Rochester. Because the evidence is sparse, the surname is best understood as a rare English name with local and occupational associations rather than a single fixed origin.

Fun fact
Lower records a Sussex peasant using rochester to mean a baptismal register, showing how closely the name could be tied to local speech and parish life.
