Keyser
A surname usually meaning “emperor,” often a German or Dutch form related to Kaiser/Caesar.
The #4,446 most common surname in the United States (2010 Census) — about 1 in every 38,700 Americans shares it.
Etymology
Keyser is a spelling variant of German Kaiser and Dutch keizer, both meaning “emperor,” ultimately from Latin Caesar. In surname use, it likely began as a nickname or descriptive byname for someone associated with imperial authority, or simply as a Germanic form of the title. English records also show it as an imported continental surname, especially in immigrant communities.
History
The historical sources treat Keyser as a continental import into English-speaking areas, especially from Germany and the Low Countries. Variants such as Kaiser, Keiser, Kaser, Kayser, and Keyzer appear in early records and later American usage. In Dutch naming practice, similar forms could also reflect house names or signboard-style identifiers rather than direct descent from an emperor.

Fun fact
19th-century surname writers often grouped Keyser with surnames meaning “king,” “queen,” and “prince,” because all were built from titles of rank.
