There is a Bilbo, and a hobbit in the Associated Words list (assuming that is a common misspelling there, and not something more fraught), but no match.
Then again, there is a Martin in the clues, but no Freeman (unless there is a bastardized anagram in Manfred Mann somehow).
I keep finding names in truncated versions of clue names. For instance, there is a Rivers and an associated word of Idaho, and River Phoenix starred in My Own Private Idaho, but I can't find anything else that completes that match. There is a Rains, and River's sister's name is Rain (originally Rainbow, but wth), but Rain had nothing to do with My Own Private Idaho.
I'm not sure what the "different form" Frank referred to is, but perhaps Bernard of whatever should be referred to as Saint Bernard for whatever fist name/last name/ pairing Frank has going.
One of the Associated words is 22, and Bernard King wore that jersey number, but I can't find any other matches like that.
Frank said he thought this Tangredi was easy, so I may be overthinking things.
Cecil Day-Lewis certainly seems to suggest Daniel Day-Lewis, but I can't find and Associated word that would go with him.
There's a Redi in this puzzle, but no Tang that I can find.

Again with the dropping part of a name and anagramming, Angela Burdett-Coutts could go with Harper Lee (since Coutts anagrams to Scout, without the extra T)
Matthew Boulton, without the extraneous U could pair with John Locke to form neocon John Bolton
Seward's first name is William, and Dershowitz's is Alan.
All I've thought of, for now.
