The wedding of Princess Madeleine, Duchess of Hälsingland and Gästrikland, and the British-born American financier Christopher O'Neill took place in Stockholm on 8 June 2013.

Princess Madeleine is the second daughter and youngest child of King Carl XVI Gustaf and Queen Silvia of Sweden.

Christopher O'Neill also did not change his last name, unlike his brother-in-law Daniel, husband of Crown Princess Victoria.

[14][15] In May 2013, the Marshal of the Realm Svante Lindqvist announced that O'Neill had asked not to be granted royal status and to remain a private citizen.

O'Neill is Roman Catholic and the couple intended to continue residing in New York immediately after their wedding (but later moved to London, England for a few years), but their children will have to be raised in Sweden and as Lutherans, like their mother, in order to have succession rights.

[18] On 7 October 2019 Madeleine's father the king issued a statement rescinding the royal status of her three children in an effort to more strictly associate Swedish royalty to the office of the head of state; they are still to be styled as princesses and prince, as well as duchesses and duke of their provinces, and they remain in the line of succession to the throne.
