Yup, Heroes of Altamira has it's own Don Miguel...and he's a Knight of the Rose and Cross...
EDIT: so the newcomers reading this (and especially Dr. Miguel Contraras) can get in on the joke, the character I've been playing (for about a decade now) in the Crimson Valor campaign (another 7th Sea living campaign) is Don Miguel Orozco de Torres y Reina del Mar del Castillo. He is, of course, a Knight of the Rose and Cross.
And to answer your unasked question, No he will not show up in this campaign (though he does have a small part to play in two player's backgrounds but that's because the first player is my son, and the second has been playing with my Don Miguel for many years now). So you can rest easy, there will be no Mary Sue's...
