The family coat of arms is described as "Porte d'azur a l'escusson d'argent a .d'or en chef, Cry Wavrin" from page 194 of Historie Genealogique des Pais-Baseou Historie de Cambry et du Cambresis published in 1664. It is one of the ancient families, because in the registers of the Abbeys of St. Bertin and Cercamp, one finds concessions or grants made in the year 1160 and 1180 by Robert and Jean de Beauffremez, Chevaliers, in a cadet branch of the House of Wavrin.
