Do we know who were Margaret Beaufort’s ladies in waiting in around 1461?

Hello again! I posted here recently- I’m currently writing (or trying to write, rather) a piece of historical fiction set to the backdrop of the war of the roses (a novel hopefully).

One of my supporting characters is Margaret Beaufort. Do we know the names of her ladies in waiting or any other servants of hers who may have been in the picture around the time of the battle of Towton? If we don’t know, I’ll make someone up- but as far as possible if there’s a real figure who we have some knowledge of, I’d like to include them. Thanks!
