Historical Fiction I would recommend taking into account the books you mentioned is the author Bernard Cornwell he has many novels set in different historical times. The most famous of which is probably the Sharpe books, which was made a tv series starring Sean Bean. I have read only a couple of the books, but I enjoyed the Sharpe TV show.
Other Authors I can recall from in this genre is Sir Walter Scott who has a historical novels set in the Jacobite rising like Waverley . Other Famous books of his are Rob Roy and Ivanhoe (which is set in in the same time Robin Hood takes place). My favorite is the more obscure Quentin Durward, possibly because I saw the film with Robert Taylor first.
For more Swash buckling historical Fiction- Rafael Sabatini I enjoyed Scaramouche, and Captain Blood which were both made into films.
Historical fiction that can be read to kids - Books by Robert Louis Stevenson (Treasure Island, Kidnapped , and The Black Arrow) & The Children of the New Forest by Frederick Marryat which is about the lives of a Royalist Family during the time of the English Civil War.
For Children’s Fantasy I can’t recommend Diana Wynne Jones enough. The Chrestomanci series is great. Dark Lord of Derkholm is a favorite of mine because it is a extremely well done parody of the Fantasy Genre (Its noce to read the sequel to the book as well to know wheat happens to the characters). She is also the writer of Howl’s Moving Castle which Hayao Miyazaki based a film out of.
