Edmond de Coussemaker sang regularly in his region (Belle, Aire-sur-la-Lys, Kassel...), interpreting his own melodies or the fashionable "airs lyriques". Even an opera was performed, "Le Diamant perdu" ("The Lost Diamond"), in 1835. He left the composition of another opera, "Imogène", unfinished. In 1836, in his native town, he married Marie Ignard de la Mouillère, to whom he dedicated a whole series of romances during their period of engagement. If his output does not bear testimony to an exceptional talent, his works are nevertheless firmly constructed and reflect the taste of the Restoration. He had a significant influence on production in the region, orientating it towards gothic romanticism in the so-called troubadour style. He became a judge at the District Court of Sint-Winoksbergen in 1843, after which he was appointed to the Court of Hazebrouck in 1845. Eventually, he became judge in Rijsel in 1858. In 1874, he was elected Mayor, "maire", of Bourbourg, his last residence.
