On 10 June 1672, he married Sophia Dorothea of Schwarzburg-Arnstadt (8 June 1647 – 26 April 1708).
Henry Ernest, Count of Stolberg (20 July 1593 in Schwarza – 4 April 1672 in Ilsenburg) was a German nobleman.
By 1904 he had founded three Landerziehungsheime, based on Reddie’s model, for boys of different ages, in Ilsenburg, Haubinda, and Bieberstein.
During the 30 Years' War the castle of Wernigerode, occupied by Henry Ernest, had fallen into such a state, that he moved his court to Ilsenburg in September 1648.
In the years 1775-76 Count Henry Ernest of Stolberg-Wernigerode had a grand hunting lodge built on the Königskoll in the Huysburger Häu south of Ilsenburg.
