Henry Sinclair of Lybster

He had a wadset of Lybster, where he eked out a living as a customs officer.

"The Master had also a natural son, Henry, who got a conveyance from his brother, Earl George, of part of the lands of Borrowstown and Lybster, with "the miln and fishings", and in a reversion by him in favour of the Earl dated 23d September 1606, he is designed as his "brother naturall". By his wife, Janet Sutherland, he had a son John, and he is probably the ancestor of a family of Sinclairs of Lybster, who occur as Wadsetters of these lands down to 1670.

"In 1614, Henry Sinclair accompanied Earl George in an expedition to Orkney, and it is related by Gordon that, while besieging the Castle of Kirkwall, he "went to bed at night in health, but before the morning he was benummed in all his sences, and remained so until his death", - an event evidently considered by the historian as a judgment on the Earl's proceedings." (John Henderson, Caithness Family History (1884)).
