Duke of Windsor did, Prince Michael of Kent did.

For the matter. Prince Richard, Duke of Gloucester (who as senior member of the House of Saxe-Coburg-Gotha, is in the line of succession - 20^th, right after 12yr old Master Arthur Chatto) married Birgitte van Deurs, daughter of Asger Henriksen and Vivian van Deurs. (Danish)
