Eysteinn

Adapted from the Old Norse name Øystæinn, Eysteinn is an Icelandic variation, likely meaning "island of stone" or perhaps "stone island". Also appearing as Øystein in Norway, Östen in Sweden, and Ùisdean in Scotland, this form is predominantly used in Iceland and has been notably borne by a 6th to 7th-century semi-legendary king of Sweden, by the 14th -century poet Eysteinn Ásgrímsson, and by actor Eysteinn Sigurðarson.

Another interpretation of the name is that it means "island of good fortune" or "island of luck".

Pronounced AY-stayn.
