While David II is holding on to the throne but failing to sire an heir, his nephew Robert Stewart (whom he can’t stand, remember) is doing almost the exact opposite. He may not have the throne but while he waits to see if he’s going to get a crack at the top job, he fathers lots and lots of heirs. In fact, when David II dies and Robert ascends to the throne (as Robert II, first of the Stewarts) his tally of kids is estimated at over 20. He has so many grown-up sons, in fact, that he could run his own jousting tourney. All looks rosy for the Stewarts - but Robert II is 55 and his sons are no longer children. They are grown-up aristocrats each with their own desires and ambitions. They might get fed up waiting around...
