Horatio Sharpe was born in England in 1718 to parents William Sharpe and Margaret Beake, of Beak Street, Picadilly and Elstree in Hertfordshire. He was one of sixteen children, of whom nine brothers and four sisters survived their father, William Sharpe, Sr.  – Sharpe's older brothers were William, John, Nicholas, Joshua, Thomas, Charles, Gregory, and Philip Sharpe. His four sisters were Mary, Elizabeth, Gulielma-Maria and Anne. His brother Gregory Sharpe (1713–1771) was appointed Master of the Temple in 1763 and was chaplain to George III. His brother William Sharpe of Brocklee Hill, Elstree in Hertfordshire (b. abt 1696-d. 1767) was Clerk of the Council. His brother John Sharpe Esq. of Lincoln's Inn (abt 1700-1756) was Solicitor to the Treasury.
He was commissioned in the King's forces in 1745 as a Captain and fought in the Jacobite rebellion against the Scots. He served with the 20th Regiment of Foot and the Marines. Later he is found in the West Indies as a Lieutenant-Colonel. He served until his appointment by Frederick Calvert, 6th Baron Baltimore as the proprietary Maryland colonial governor. (Following Samuel Ogle, who had died.) Horatio Sharpe was the brother of Lord Baltimore's guardian (William). He arrived in Maryland in August 1753.
Appointed by the King in 1754 as the Royal Commander in Chief of all British Forces and commander of colonial forces for the protection of Virginia and adjoining Colonies, Sharpe was superseded by the arrival Maj. Gen. Edward Braddock in 1755. Prior to Sharpe's service, Colonel James Innes had commanded all provincial soldiers.
He was a capable civil and military administrator, gentleman-farmer, fancier of fine horses, hospitable host, and friend of George Mason and George Washington. (Source: Jim Bartlinski, Carlyle House Curator, 14 Feb 2006)
Horatio Sharpe also built Whitehall on the outskirts of Annapolis (Whitehall Road, Skidmore, Anne Arundel County). Now a National Historic Landmark, Whitehall was designed by Joseph Horatio Anderson, who was also the architect of the Maryland State House. It served as Sharpe's residence from the time of his enforced retirement in 1769 until his return to England in 1773.
Return to England
He returned to England to attend to family matters in 1773 and remained there until his death in 1790. In the Maryland Confiscation Act of 1780, Horatio Sharpe is specifically mentioned by name. He was encouraged by the new state of Maryland to return from England to Maryland and reclaim his lands. Barring that, he was permitted to sell or dispose of all his Maryland properties. Sharpe sold or gave his Maryland properties to his long-time secretary, John Ridout, who had stayed in Maryland during the Revolutionary War to protect his former employer's property.
Sir Robert Eden, 1st Baronet (1741–1784) was the last Royal Governor of Maryland. He followed Horatio Sharpe as governor in 1769.
