Turgesius

Turgesius was a Viking chief active in Ireland during the 9th century. Turgesius Island, the principal island on Lough Lene, is named after him. It is not at all clear whether the names in the Irish annals represent the Old Norse Thurgestr or Thorgísl. John O'Donovan and Charles Haliday independently identified him with Ragnar Loðbrók, but the identification is not generally accepted.
