"... St. ___, I met a man with seven wives" (rhyme snippet) (4)
I believe the answer is:
ives
(Other definitions for ives that I've seen before include "US composer, Charles" , "This classical composer" , "Charles -, American composer (The Unanswered Question)" , "American composer of Three Places in New England, d. 1954" , "Saint of Cornwall or Cambridgeshire" .)
