Bolleville, la Manche
Pierre François Desiré Bihet and his parents ( Jean Marc Desiré Bihet & Josephine Brochard ) came from Bolleville, Canton de la Haye du Puits, Manche, Normandie. His wife, Marie Ann Desiré Picot, was from la Bonneville, Canton de Saint Sauveur le Vicomte, a village 11 miles to the north east.
Bolleville is just 11 miles inland (SW) of Barneville-Carteret, familiar to Channel lslanders due to the ferries there from the islands.
