I know this an old post but I just came across it. Saegan is a celtic male name. It's descended from the Vikings "sagan" and it means "saga, story or legend". I wanted to use Sagan with my first child but couldn't because my husband is Swedish and it wouldn't translate well. Saegan was a Celtic cheiftan and son of a Viking. I recently named my second son Saegan after a friend researched the name for me in Gaelic and traced it back. Being a Scot, this was a perfect name for our son. He is the story of a Viking and a Celt.
