I believe the answer is:
anne
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">last stuart monarch</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for anne that I've seen before include "Name of queen or princess" , "18th century Queen" , "Boleyn or Hathaway, say" , "First name of two of Henry VIII's wives" , "One of two Henry VIII wives" .)
