Duke Georg August of Mecklenburg-Strelitz

He was born in Neustrelitz as second son of George, Grand Duke of Mecklenburg-Strelitz (1779-1860) and his wife Marie (1796-1880), daughter of Prince Frederick of Hesse-Kassel and Princess Caroline of Nassau-Usingen. His paternal grandparents were Charles II, Grand Duke of Mecklenburg-Strelitz and Princess Friederike of Hesse-Darmstadt.

His sister Caroline Mariane married Frederick VII of Denmark. On 1860 his elder brother Frederick William succeeded their father as Grand Duke of Mecklenburg-Strelitz.

George August died on 20 June 1876 in St. Petersburg, at the age of 52. The line of his son George soon died out; since his first son had married morganatically, his second son Charles Michael became titular grand duke of Mecklenburg-Strelitz.

On 16 February 1851 in St. Petersburg, George August married Grand Duchess Catherine Mikhailovna of Russia (1827-1894), daughter of Grand Duke Michael Pavlovich of Russia and had issue:
