I am totally confused about Sunniva. I first thought it is English and Synnöve (or Synnove with a string through the o) is the Norwegian version to it. The legendary Sunniva who traveld to Scandinavia was from Ireland. Was her name Sunngifu before it became Sunniva in the North of Europe?
Every name book I ever read mentioned Fridolin as derivation or even nickname to the German name Friedrich. However there was Fridolin the patron saint of animals. He was from Ireland. Could Fridolin be of Irish origin?
