In 1855, Hermine de Kerret married Georges Blanchet de la Sablière, with whom she had five children. The household resided in the Domain of Lanniron, near Quimper, whose lands had been inherited from Charles Fidèle.
At the death of Carl, Hermine’s brother, the couple transferred ownership of the Gouesnac’h property to their son Georges, who was born in 1863. Georges, then 24 years old, had inherited his love for adventure as well as his artistic talent from his uncle Jean René Maurice de Kerret. On December 2nd, 1852, at 19 years of age, the latter set sail for the French Pacific Ocean naval station, situated between Tahiti and the Marquis Islands. His role on the frigate « La Forte » was that of draughtsman. Besides the memory of four years of adventure, he compiled over 200 drawings of lands and people he had encountered in a book, « Journal de mes voyages autour du monde 1852-1855″. This fascinating record appears in a magnificent work by Tugdual de Kerros-Malakoff.
At 19, Georges himself explored the Svalbard archipelago and the famous island of Spitsbergen. Two years later, he found himself on the great northern plains of Russia. In 1884, his journals and photographs earned him membership in the Société de Géographie, then presided over by Ferdinand de Lesseps. After another two years, during which he completed a doctorate in law, he crossed the Atlantic by liner and then the American continent by rail. Continuing up the Pacific coast by steamship, he reached Sitka island where he became friendly with the Tlingit people, studying their customs and way of life. His were the first precious photographs of the region, and on his second voyage in 1889, he came equipped with a Mackenstein travel camera which he had bought in Paris from a certain Nadar.
Georges hunted bear with his Winchester, went salmon fishing with the native people, attempted to climb Mount St. Elias, and rubbed shoulders with gold diggers.
His head swimming with ideas for various projects, Georges finally hung his hat at Gouesnac’h, where in 1893 he married Marthe Hascoët de Saint-Georges. As the residence above the stables at Boutiguery was no longer large enough to accommodate the family, new plans for a future chateau were drawn up by the architect André. Even as the Kersanton stone was being quarried, plans were being made for the construction of the new building at the highest point of the Domain, in the field to the east of the stables. Georges, now mayor of Gouesnac’h, founded the Ecole des Soeurs, put the Domain’s brickworks back into working order and prompted the construction of the slipway and quay at Pors-Meillou. These were necessary for the loading of bricks as well as firewood for the pottery works at Quimper, and for the unloading of maerl (a mixture of seaweed, seashell and sand traditionally used for agricultural purposes in coastal Brittany, being an excellent soil amendment due to its high levels of magnesium, iron and trace elements). In addition, he donated the port access road to the municipality. In 1898, at the age of 35, Georges contracted typhoid fever and died, leaving behind his young widow and three small children.
Marthe, in the interests of her family, moved to Quimper. Her son Carl, who was born in Lanniron in 1895, pursued his studies at boarding school in Pontlevoy, near Tours where he passed his baccalaureat before joining the army at the age of 18 just as the First World War broke out. He survived the war and returned to Boutiguery to start a family, marrying Marguerite de Mandell d’Ecosse de Latour-Maubourg, with whom he had four children. Carl abandoned his father’s plans to build a castle, opting instead to transform the stables into an Anglo-Norman-style cottage.
Like his father, Carl had a love of sailing. This passion led him to win a gold medal at the Amsterdam Olympics of 1928 on board « Aile VI », the boat of Virginie HÈriot, viscountess of Saint-Sénoch and a talented sailor. Carl also had many boats built from his own plans. A lover of the forests on his lands, he began a small collection of about 150 Rhododendrons and Azaleas. During the Second World War, he joined the Resistance. Arrested by the Gestapo, he miraculously escaped deportation thanks to the bombardment of the Rennes train station by the allied forces the night before he was due to depart. Carl Blanchet de la Sablière passed away in 1979 and left his home to his youngest son, Christian, who was born at Boutiguery in 1931.
