Well, my name's actually spelled differently from this, but it's basically the same name.
[gotten from http://www.behindthename.com]
SHANNON

Pronounced: SHAN-un

From the name of the Shannon River, the longest river in Ireland. It is composed of the Gaelic elements sean "old, wise" and abhann "river".

Mine is actually spelled Shanin, not the Shannon [my parent's are just freaking weird.]

My middle name is a form of "Christine" [Christee, again. Parents are weirdos.]

CHRISTINE

Last name:

DUNCAN
Gender: Masculine

Anglicized form of the Gaelic name Donnchadh which means "brown warrior", derived from Gaelic donn "brown" and cath "warrior". This was the name of two kings of Scotland, including the one who was featured in Shakespeare's play 'Macbeth'.

Huh...Funny that it shows what my lineage is. Just goes to show that I DO have Scandinavian blood in me...yay for the Vikings.

But yeah. That's me.
