Trygve

Trygve is a given name for males used throughout Scandinavia, but is perhaps most common in Norway. Trygve is derived from the Old Norse tryggr, meaning "true, trustworthy", cognate with Old English treowe, Old High German triuwe. Gothic has triggws "πιστός". The Old Norse form of the name was Tryggve or Tryggvi, e.g. Tryggve Olafsson (d. 963).
