Frederick Lewis Maitland (19 January 1730 – 16 Dec 1786)[1] was a distinguished officer of the Royal Navy.

John Maitland successfully defended Savannah against a combined French and American siege in 1779.

He moved to take command of HMS Elizabeth in 1778, and in 1782 found himself serving under Admiral George Rodney.

The eldest son, Charles went on to inherit the estates on his father's death and assumed the surname Makgill.

He married a woman named Mary Johnston and the union produced a son, David Maitland Makgill Crichton (1801–1851).
