Baron Aschwin of Sierstorpff-Cramm (German: Freiherr Aschwin von Sierstorpff-Cramm; 29 March 184614 October 1909) was a German nobleman who was the chamberlain of the Duchy of Brunswick.
Aschwin of Cramm was born at the village of Lohndorf in the Kingdom of Bavaria, German Empire, as the third child and first son of Adolf of Cramm (1812–1879), and his wife, Hedwig of Cramm (1819–1891).
Aschwin married on 24 September 1872 at Bad Driburg to Baroness Hedwig of Sierstorpff-Driburg (1848–1900), member of a Prussian noble family. She was daughter of Count Ernst of Sierstorpff-Driburg (1813-1855) and his wife, Baroness Karoline of Vincke (1822-1870).
They had four daughters:
In 1881, Aschwin added the last name of his wife (Sierstorpff) to his own, since his father-in-law was the last male surviving heir of the Sierstorpff family name and estate.
Aschwin was hereditary chamberlain of the Duke of Brunswick. Later he served as Master of the Horse where he met with the Sultan of the Ottoman Empire. He settled on his estate of Reckenwalde, Province of Brandenburg (now Wojnowo, Poland).
