books about the famous English people of Middle Age (descendants of the Royal f)

Hello,friends!
can you advise me some useful books about famous people of the middle age? I am interested in the descendants of the royal family who did not reign
I don't know how to find them.
at the moment I have found one interesting book in the free scientific library:

But i am interested in other books;medieval English art, literature, weapons,man's life...
Thank you!
