Sub Rosa #14 & #15 have two piles of mythical wizard bloodlines. I was pleased with them, but I'm the author and so I'm biased. I tried to go by regions, so that might help.
The reviews for 14 are here and here and here.
The review for 15 is here.
Responses have been positive. Here's the entry for Morgana Le Fey from #15:
Morgana Le Fey
Morgana is a creature of conflicting and mysterious heritage. She is a queen of Avalon, she is the sister of King Arthur, she is a student of Merlin, and she is the mother of Oberon by Julius Caesar. All of this implies she is mortal and yet she is also Faerie, contemporary to King Arthur and yet predates him. Morgana was said to be the wife of King Urien and the mother of Yvain, some stories make her the mother of Modred. She dwells either in Avalon with her lover, King Guingemart or in an equally mysterious realm known as the Perilous Vale, where she trapped Sir Lancelot and other knights of the Round Table several times. She hated Guinevere for exposing her affair with Guingemart and chased Lancelot, both because she had feelings for him and to hurt Guinevere. Morgana kept many lovers, though, including the knights Accalon of Gaul, Helians, Kaz, Gui, and Corrant. She fashioned several items in attempts to disrupt Arthur’s court- a mantle which set its wearer ablaze, a false Excalibur, and a drinking horn which only spilled its contents when the bearer was unfaithful. She also provided healing potions to several knights before leaving Arthur’s court and helped carry King Arthur away to Avalon to sleep and heal his wounds after the Battle of Camlann.
This bloodline is also appropriate for wizards with Faerie Blood (minor).

It's important to note there's a story element to Mythic Bloodline that adds something beyond the mechanical benefits-- your wizard is part of a heritage, a line of wizards traced back to powerful ancestor, and therefore an heir of sorts. That may have a currency in some situations, far more than if you just had the Virtues and Flaws. It means that a wizard's provenance can mean something in the game, and you'd like the Storyguide to consider that when creating the stories.
