[quote name='Night Watchman' post='1433531' date='Jul 9 2008, 14.32']Not Really a Referance or anything, but I wanted to point out that 'Lann the Trickster is probably the origin of Lannister.[/quote]
It is probably a nod to Loki who is a Trickster as well and father of giants.
I noticed the name Daeron appears in the Silmarillion as a minstrel as well at the court of Thingol who betrayed Luthien twice because he wanted her himself. Thinking this is where the name of the Nightwatchman that Arya kills came from.
