Kayser (surname)

Kayser is a surname derived from the German imperial title Kaiser (English: emperor). The title Kaiser is in turn derived from the Latin title Caesar, which again is a derivation from the personal name of a branch of the gens (clan) Julia, to which belonged Gaius Julius Caesar, the forebear of the first Roman imperial family. The further etymology is unclear.

Other names with the same origin are Kaiser and Keiser, and Kiser; Keyser is more common as a Dutch spelling, Kiser is more common in Sweden and the United States, and Qaisar is an Arabic version.
