Sir Alexander Bosville Macdonald, 14th Baronet

His paternal aunt, Julia Louisa Bosville, married his maternal uncle, Henry Willoughby, 8th Baron Middleton.

[2] Less than a month after his birth, he became de jure 14th Baronet Macdonald, of Sleat, in the Isle of Skye, County Inverness, in the Baronetage of Nova Scotia.

Upon the death of his great-grandfather, Godfrey Macdonald, 3rd Baron Macdonald, 11th Baronet, in 1832 the baronetcy reverted as his three eldest children were born before his marriage to Louisa Maria La Coast (said to have been the illegitimate daughter of Prince William Henry, Duke of Gloucester and Edinburgh, himself a son of Frederick, Prince of Wales and a younger brother of King George III), so they were considered illegitimate, while the ten children born after their marriage were considered legitimate.

[1] From his father, Sir Alexander inherited the c. 1655 Arcadian Shepherds by Giovanni Benedetto Castiglione, and the c. 1563 The Miraculous Draught of Fishes by Joachim Beuckelaer.

[12] Both stayed in the family until the early 1907s when they were sold by his great-grandson, Sir Ian Bosville Macdonald, 17th Baronet.
