Ben is frequently used as a shortened version of the given names Benjamin, Benedict, Bennett or Benson, and is also a given name in its own right.
Ben (in Hebrew: בֶּן, Son of) forms part of surnames, e.g. Abraham ben Abraham (Hebrew: אברהם בן אברהם). Bar-, "son of" in Aramaic, is also seen, e.g. Simon bar Kokhba (Hebrew: שמעון בר כוכבא).
