From Blueblood's page:

Lauren Faust stated that Celestia's nephew had no name in the show (before The Best Night Ever aired), and that he's the "great great great great great great great great great great great (and probably even more greats) nephew on Celestia's and Luna's mother's side, about 52 times removed, roughly speaking." He was originally a Duke but was changed to a Prince per Hasbro's request.

It's possible that Cadance is also a 52 times removed niece from Celestia's and Luna's mother or father, cause if there's that many greats there's gonna be at least more than one child
