In Game of Thrones News...

[Lord Dane]

Supposedly the Red Wedding has its basis in history.  The Black Dinner of 1440 in Scotland, where the 6th Earl of Douglas was murdered.  At the end of the dinner a black bull's head was brought into the feasting area (a symbol of death), and then the Earl and his companions were subdued and beheaded.

As I understand in the books Talisa was not present at the Red Wedding, and thus wasn't brutally murdered at it like in the show.

Correct. Also, The Wall was influenced by Hadrian's Wall in England/Scotland. And Talisa was not the original bride in the books. It was Jeyne of House Westerling who married King Robb.

Yup...and Jeyne wasn't murdered at all.  Nor was she present at said wedding.

I was thinking after talking with a friend about it, that Game of Thrones is based alot on the War of the Roses as well.  The "Lannisters" in the show definitely have some resemblance to the Lancasters of history.

I was looking into the story & regions of Westeros on the actual story line ...
According to recall accounts from Jaime Lannister, Ned Stark, and others, the most notable knight they have ever known in person was Ser Edric of House DAYNE, Lord of Starfall in Dorne. He is the one who leads the Brotherhood of No Banners in the Riverlands who held Arya Stark as their guest for a time & who fought the Hound when he was captured. They put alot of detail into this story.

That was Edric?  I could have sworn it was Lord Beric Dondarrion who led that brotherhood, along with Thoros of Myr.  The Hound actually 'killed' Beric, but Thoros brought him back w/the kiss of life (which I've always assumed was a mystical form of CPR).

At least that is what is written in the books themselves.  Is this from the show's storyline?  I've noticed a few things that have been changed for the show from the novels.

As for the Sword in the Morning that is remembered and revered the most, that would be Ser Arthur Dayne.  From the Wiki (easier than finding the actual page in the book)

"Eddard recalls that Arthur Dayne was the finest knight he ever saw. Jaime Lannister and Barristan Selmy also recall him with the highest degree of respect."

And I stand corrected on Edric Dayne being part of the Brotherhood...I must've skipped right past that; for the rest of the books there's little mention made of Edric, Beric being the main leader by the time they meet Arya, who was in the company of the Hound until she got away from him.
