Baron Macdonald

Baron Macdonald, of Slate in the County of Antrim, is a title in the Peerage of Ireland. It was created in 1776 for Sir Alexander Macdonald, 9th Baronet, of Sleat. The Macdonald family descends from Uisdean Macdonald (died 1498), also known as Hugh Macdonald, illegitimate son of Alexander Macdonald, Earl of Ross. On 28 May 1625, his great-great-great-great-grandson Archibald Macdonald was created a baronet, of Sleat in the Isle of Skye in the County of Inverness, in the Baronetage of Nova Scotia. The baronetcy was created with remainder to heirs male whatsoever and with a special clause of precedence which provided that it should have precedency over all former baronets (Sir Robert Gordon excepted).

On 23 December 1716 the fourth baronet, Sir Donald MacDonald, was created Lord Sleat in the Jacobite peerage.

The first baronet's great-great-great-grandson, the ninth Baronet, was raised to the Peerage of Ireland as Baron Macdonald, of Slate in the County of Antrim, in 1776. Lord Macdonald married Elizabeth Diana Bosville, daughter of Godfrey Bosville. Their eldest son, the second Baron, represented Saltash in Parliament. He never married and was succeeded by his younger brother, the third Baron. He was a Lieutenant-General in the Army. In 1814 Lord Macdonald inherited the Bosville estates of Thorpe and Gunthwaite in Yorkshire through his mother, and assumed by Royal licence the surname of Bosville in lieu of Macdonald the same year. However, on inheriting the Macdonald estates on the death of his older brother in 1824 he resumed by Royal licence the surname of Macdonald after that of Bosville. In 1803 Lord Macdonald married, in an English ceremony, Louisa Maria la Coast, illegitimate daughter of Prince William Henry, Duke of Gloucester and Edinburgh (grandson of King George II). The couple had previously married in a Scottish ceremony in 1799. However, the validity of the Scottish marriage was disputed, and as a result the eldest son of Lord Macdonald born before his 1803 marriage, Alexander William Robert Bosville, was not allowed to succeed his father in the titles (this decision was later challenged; see below). He was therefore succeeded by his eldest son born after the 1803 marriage, the fourth Baron. His great-grandson, the seventh Baron, served as Lord Lieutenant of Inverness from 1952 to 1970. As of 2013^[update] the barony is held by the latter's eldest son, the eighth Baron. He is Chief of the Name and Arms of Macdonald (see Clan Donald).
