For all that Charles I led England into a civil war and then lost his crown and, well, head, he was at least one half of a happy marriage. For an institution once upon a time comprised mainly of foreign alliances and quiet desperation, that’s something, no? After a rocky start, Charles and Henrietta Maria of France settled into the kind of complacent domesticity to which political matchmaking aspired, and from this came nine children. Two of those sons – Charles II and James II – would end up kings. A daughter, Mary, would become the mother of another – William III. And another daughter, Henrietta Anne, would marry into the French Royal Family and end up a dazzling fixture at Versailles.
