Ooh~ These are both lovely choices. If you'll allow me, though, there are four essences that I think would be a great fit for Elizabeth.
The first would be Dorothy Gale from the Wonderful Wizard of Oz. (Heck, you could probably even take her from the movie version, since that one is old enough.) Silver or ruby slippers to protect her from harm, a flash step triggered by clicking her heels, perhaps a little extra charisma when trying to persuade or calm down Blots (the game's NPCs, which can be humanoid or beast-like). An ironic quirk there would be homesickness if away for too long (where she identifies as home is up to her).
The other two are more obscure tales on the more obscure side which features ladies that might suit Elizabeth VERY well: Bluebeard and The Girl Without Hands. For Blubeard's wife, Elizabeth could unlock any door, possibly even make short-range portals, at the cost of her blood, and a quirk could be either heightened curiosity or heightened disobedience. For the Girl Without Hands, Elizabeth's whole hands could be made of silver now (possibly quite durable), and would feature most of silvers magical/holy properties in repelling evil beings. Her tears could also be magical too: healing tears for allies and/or tears that can repel evil as well. (Also... pear-shaped grenades. Because it amuses me.)
