Kilravock Castle, ancestral home of The Rose line since approx 1293. A Norman Family, headed by one Hugh de Ros, that came with William the Conqueror. Oldest held line/castle to continue to go from father to a son without break in Britain I believe. If the genealogies are to be believed, my maternal grandfather, Melvin Alan Rose, was a direct, father to son descendent of the line as well, though not in serious contention for Head of Clan. That would mean my Uncle Roy, and his son Donavan, would also be direct line male descendants.
