II. William, second Earl of Caithness, in consequence of his father’s resignation, obtained from King James III to ‘William Sinclare, son of William, Earl of Caithness and Lord St. Clair, begotten betwixt him and Marjory, Countess of Caithness, his spouse’; a charter of the whole lands of the earldom of Caithness, etc., to be held by him and his heirs whomsoever, dated 7 December 1476.

There are indications that this Earl was out of favour with King James IV, which may have been occasioned by the great disorders that took place in Caithness in the latter years of the Earl’s life. But he manifested his loyalty by accompanying the King on his expedition into England and shared his fate on the field of Flodden, 9 September 1513.

He married Mary, daughter of Sir William Keith of Inverugy, by whom he had two sons:

1. John, third Earl of Caithness.
2. Alexander Sinclair, who in a Crown charter of 18 July a1527 is called ‘brother’ of John, Earl of Caithness. …

The Earl had also a natural son, William, who was legitimated under the Great Seal on 5 april 1543.
