it almost did, 1 time, that i know of. there was a story at the early of the 20th century, when nicholas II of russia's 2 oldest daughters, olga and tatiana, had "reached marriagable" age, as to who they could/would marry. when the idea that a japanese prince came up, they both basically said that would be peachy keen, with the exception that they could never marry a pagen. later on, they added the excuse that they didn't want to leave russia, a fact of which could've saved their lives. just something i read, i believe, over at the alexander palace time machine/msg board, a while back.
