Details about Anne/ Anna Mackay's first husband, Alexander MacDonald. He apparently died quite young (at least by 1657). 5. Alexander [MacDonald] of Paiblisgearry, in North Uist. In 1653 he married Anne Mackay, sister of John, Lord Reay, and by her had issue — (a) Captain Hugh Macdonald, who succeeded. (b) Barbara, who married Lachlau Maclean of Torloisk. Alexander died in or before 1657, as his wife appears on record as a widow in the course of that year. Hence in Sir James Macdonald's Deed of Entail, in 1658, his name dues not appear along with the Baronet's other brothers. Captain Hugh Macdonald of Paiblisgearry succeeded his father. He also appears on record as of Duistill, in Sleat. He was brought up evidently under the Reay influence, which was anti-Jacobite, and favourable to the Orange movement. He held the rank of Captain in the regiment of General Mackay, his relative, and had the freedom of Montrose conferred on him in 1692. Much of his military life was passed in Flanders, where he fought in the army of the States General in the war with France. He died before 1721, when he was succeeded by his son, John Macdonald of Paiblisgearry, who appears that year in an enumeration of the gentlemen of North Uist. We have no information as to the date of his death, but with him the descendants of Alexander of Paiblisgearry terminated in the male line. http://www.ebooksread.com/authors-eng/angus-macdonald/the-clan-donald-volume-3-dca/page-34-the-clan-donald-volume-3-dca.shtml
