Prince Charles proposed to Diana in February 1981; she accepted and they married in St Paul's Cathedral on 29 July of that year. Upon his marriage, Charles reduced his voluntary tax contribution from the profits generated by the Duchy of Cornwall from 50% to 25%. The couple lived at Kensington Palace and at Highgrove House, near Tetbury, and had two children: Princes William (b. 1982) and Henry (known as "Harry") (b. 1984). Charles set a precedent by being the first royal father to be present at his children's births.
