After the German occupation of the Channel Islands during the Second World War, the later barons lived mostly at their Shrubland Park estate, near Ipswich, in Suffolk. the titles are held by the fourth Baron's great-grandson, the seventh Baron, who succeeded his father the sixth Baron in 1991. Although born and brought up in Suffolk, in April 2006, after the death of his mother, the present Lord de Saumarez sold Shrubland Park and settled in Guernsey.
