Tryggvi the Pretender

Tryggvi "the Pretender" (Old Norse Tryggvi Ólafsson, Norwegian Tryggve Olavsson) was a Viking chieftain who lived in the early eleventh century, and came from "west across the sea" (probably from the Norse settlements in England and Ireland). His story appears in Heimskringla by Snorri Sturluson, the saga Morkinskinna, and a saga composed by Oddr Snorrason on Olaf Tryggvason.
