If you ask me, the terms "Benitez Family (one of the ruling families in the Council of the Dons)" and "Medici Family (powerful, possibly ruling, family from Florence, Renaissance Italy)" should imply some similarity between the two governments.
Either way, if the Italians had a sleeper ship, it was probably destroyed and they went off on the Hispania while the French were left to fend for themselves (which could explain why Gallia hates the Houses). If the Italians didn't have one, then they probably went on the Hispania anyway. I think it's been established that the Hispania contained Mediterranean colonists, not just Spanish.
