That would depend on your point of view, as there is no 'Serbian royal family' per se. However, the last King of Yugoslavia, Peter II never abdicated, thus making his decendants the nearest thing.

Nicholas II, last Tsar of Russia, was ALSO related to the British Royal family, through HIS mother, Maria Feodorovna.
