Charles' sister Bona married the eldest son of Philip VI of France, the future John II of France, in 1335. Thus, Charles was the maternal uncle of Charles V of France, who solicited his relative's advice at Metz in 1356 during the Parisian Revolt. This family connection was celebrated publicly when Charles made a solemn visit to his nephew in 1378, just months before his death. A detailed account of the occasion, enriched by many splendid miniatures, can be found in Charles V's copy of the "Grandes Chroniques de France".
