Alexander Leith Hay

General Alexander Leith Hay [formerly Alexander Leith] (1758 – 16 May 1838), was a British army officer.

Life
Hay was born in Aberdeen on 21 December 1758, the second son of John Leith (1731–1763) of Leith Hall, Aberdeenshire and his wife, Harriet (d. 1780), daughter and heir of Alexander Steuart of Auchluncart.

He was appointed a lieutenant in the 7th Dragoons immediately on his birth, captain 1768, and colonel in the army 1794. Upon the death of Andrew Hay in 1789 he inherited the estate of Rannes, Aberdeenshire, and assumed the additional surname of Hay, being descended from that family through his paternal grandmother.

Another son, John James Leith, was a Rear-Admiral in the Royal Navy and the father of Alexander Forbes-Leith, 1st Baron Leith of Fyvie. Leith died in August 1838.
