 ==House vs family Ostrogski== might correct me, but Jogaila has not been and even if he would hawe been smoking dope, he would not could imagine to be a member of szlachta. And Ostrogski family does not qualify to be szlachta even, since they were orthodox. Lithuanian nobility probably, for quite long time. A House, since you did ask me - IMO, no. Family - yes. See Radvila family, and there is no house, despite the Grand Duchess/Qeen Barbara Radziwiłł. Best regards.
