English History Quiz -- Nobody on Twitter Got This One Yet

Quiz: Since 1066, name an English queen consort who was not the monarch (e.g. not Mary I, Mary II, Liz 1, Liz II, Anne, Victoria) who was the biological daughter of another English Queen consort, also not the monarch.

Obviously this takes an unusual situation as in a normal succession this would require her to be married to her brother, uncle, or nephew.
