Princess Augusta of Saxe-Gotha (d. 1772)
Princess Augusta of Saxe-Gotha-Altenburg (30 November [O.S. 19 November] 1719 – 8 February 1772) was Princess of Wales by marriage to Frederick, Prince of Wales, son and heir of King George II. She never became queen consort, as Frederick predeceased his father in 1751. Augusta's eldest son succeeded her father-in-law as King George III in 1760. After her spouse died, Augusta was presumptive regent of Great Britain in the event of a regency until her son reached majority in 1756.
