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.
