Jacques Pouchin, French watchmaker
Jacques Pouchin was born on September 22, 1720 in Saint-Ouen-des-Faubourgs, Bayeux, France. He was the son of Jacques Pouchin and Marguerite Mazelin who died before 1751. Jacques Pouchin married Anne-Catherine-Marguerite Covin (1728-?) On November 23, 1751 in the Église Saint-Nicolas. The witnesses are the brothers Thomas Covin (ca 1708-1761), Bernard Covin (ca 1703-1762) and tanner François Marin Richer, uncle of Anne Covin.
The date of death of Jacques Pouchin is not yet known. Perhaps Jacques Pouchin was a family of the watchmaker Gilles Pouchin who was based in Anneville-Sur-Mer around 1762, and in 1771 he was based in Les Pieux. Both places are about 100 km west of Caen, on the coast opposite the islands of Guernsey and Jersey.
Bayeux is a place in the Calvados, Lower Normandy, about 31 km from Caen. Bayeux was one of the first French cities to be liberated by the Allies after the Normandy landings in 1944 and is about 10 km from Arromanches in the Gold Beach landing strip. After the landing, one of the two artificial harbours was built off the coast. In the course of these battles at the Battle of Caen, the city was almost completely destroyed. The Nikolaikirche or Saint-Nicolas-des-Champs where Jacques Pouchin married is a church founded in the XI century in Bourg-l’Abbé Caen. This church remained intact during the war. The name Pouchin is very common in the Normandy region.
