There is no one character I can point to and say "that is it, that's her!" but a lot that I can take aspects of. It all gets jumbled up a bit to be honest as the same character can also inspire different interpretations.
No one is a better example of that than Mary Poppins.
In grade school, I forget what grade, I remember my teacher taking us all out of the classroom and we went out to this atrium area that was large and domed outside of the library and she read Mary Poppins to us. I remember being very interested in it once she mentioned Mary knew a girl from the Pleiades.
I have talked about Mary before. I have even given stats for her as a witch and as a Time Lord.
My good friend and blogger Tim Knight over at Hero Press has a trailer up for the new Mary Poppins Returns and of course, he says she is a Time Lord. I will admit I am very fond of that idea myself.
The new movie is coming out and I adore Emily Blunt. I can't think of a single thing I have seen her in that I didn't like and think she was the reason it was as good as it was.
So in the case of going back to my roots, here is Mary, as a White Witch.

Using Mary in Your Games
Mary, of course, works best when there are children about. If your game has younger children as the Player Characters then Mary practically, as she often does, invites herself in.
For me, I am planning on using her in various "flashback" episodes with the current characters.
