Many thanks to all of you for your hints. It still took me a while to get the answers because I don't like the definitions. The only one I should have got was 8d. It took me ages to work through the royal houses. At first I simply didn't go back far enough.
My FOI was 19ac, my LOI was 5ac (hopeless definition). My CODS were 19ac, 14ac and 13ac.
