Overview
Charles I de Créquy, Prince de Poix and Duc de Lesdiguières (1578–1638), was a leading French soldier of the first half of the 17th century.
Life
Charles de Créquy, ca. 1575 to 17 March 1638, was the only child of Antoine de Blanchefort (ca. 1545-1575), and Chrétienne d’Aguerre (1556-1611), Lady-in-waiting or dame d’honneur to Louise de Lorraine.
The de Créquy family were distributed throughout Northern France, with branches at Fressin, Bernieulles, Auffay and Heilly. They originated from Créquy, in Artois, which formed part of the French-speaking Southern Spanish Netherlands until annexed by France in 1659. Charles' father Antoine de Blanchefort inherited his titles and lands from his uncle, another Antoine (1531-1574), Roman Catholic Bishop of Amiens and advisor to Charles IX.
