Found a wonderful doll by Tish Tierney (Versailles Fashion Dolls) that should be perfect in my Castle Keep.  She's actually part of Tish's series of Henry VII and his 6 wives.  This was Tish's Catherine Howard who has been demoted by me to a Knight's wife living in the Castle Keep.

I also tried her in a couple of other interior settings, but prefer her in the Solar because she can be seen much better there.
