Because of the death of the sons of Sir Henry Sinclair in Spain, the Barony of Rosslyn passed directly to his grandson who was yet another William Sinclair. It was this William Sinclair who married the daughter of Malise II, the 'jarl’ of Orkney, which resulted in the 'jarldom' of Orkney eventually coming to the Sinclairs of Rosslyn. This occurred in 1379 when King Haakon VI of Norway granted the Orcadian Earldom to William's son, Henry Sinclair. This was really the peak of Sinclair power. They owned large Estates throughout Scotland plus 200 strategically placed islands in the North Atlantic - the stepping stones to the New World. Prince Henry, as he became known, was also the premier ‘jarl’ of Norway by virtue of his descent from the House of Moere. He was certainly one of the most powerful men in 14th Century Europe, controlling the northern access to the Atlantic Ocean and with a large fleet when ships represented power.
Hrolf or Rollo, as the French knew him, was the eldest son of Rogenwald ‘the Mighty’ so we have the descendants of two brothers, uniting in the offspring of that marriage. The first child to be born in 1345 was none other than Prince Henry Sinclair who, as we have said before, followed in the wake of his Viking ancestors by voyaging to the New World in 1398.
