Where the Elliott name comes from

Elliott is a surname. The English line began in Middle English as a diminutive of Elie, the Old French form of Elias or Elijah. Those names came from Hebrew and mean "my God is Yahweh".

In Scotland the surname may have a second, separate origin in the Gaelic Elloch, from a word meaning a dam or bank. The name also turns up as Eliot, Elliot and Eliott. French has Éliot and Éliott among its forms, and Swedish writes it Elliot.
