In "A Lick of Frost", it was revealed that Merry was pregnant with twins, each with three fathers; the six fathers were Doyle, Frost, Sholto, Galen, Mistral and Rhys. These six, therefore, will become her kings if and when she ever takes the throne. She has (as of "Swallowing Darkness") been specifically crowned by Faerie as Sholto's queen as well as Doyle's queen; however, she has made it quite clear that this does not mean she is bound to have either of them as her only king.
