Montennegrian and Yugoslav royal families were not the best of freinds,especially not after the exile of the King Nicholas II of Montenegro(although cousins-King Nicholas II was the grandfather of King Alexander killed in Marseilles)!It is interesting to say that Duchess Auguste Charlotte Jutta(Crown Princess Militza) was still a great friend of the family,especially of her cousin Queen Marie of Yugoslavia(born Princess von Hohenzollern-Sigmaringen of Romania),both descended from the two brothers;Marie from Eduard,Duke of Kent(Queen Victoria's father) and Auguste Charlotte from Adolphus,Duke of Cambridge(his daughter Auguste,Grand Duchess von Mecklenburg-Strelitz being her grandmother)!
