should the GM decide whether a player can create a character with more than one ancestor? I have found that nowhere in the beta text says other wise.
For example I have a Matsu Tatsuyo, whos father was from the phoenix clan. Having two family branches I chose to combine the name parts of a lion ancestor( with glorious sacrifice)[named Matsu Chiyoko] and that of a phoenix ancestor(with Imperial heritage )[named Shiba Tatsumasa].
