A document dated May 24, 1578 dealt with the succession of the deceased Jean Aubert and Marguerite L’Hotte. One of their sons, Claude was married twice. His 1st marriage, was to Michelle de Lamer, the daughter of Claude Lamer, notary and procurator to the King and Jeanne de Boussu. Claude Lamer’s marriage contract is dated March 2, 1546.
Two of Claude Aubert and Michelle de Lamer’s children are mentioned, Louis and Guillaume Aubert. An act dated September 11, 1648 mentioned a third brother, Claude. On April 22, 1644 a a legal proceeding between the inheritors of Claude Aubert (brother of Guillaume and father of Catherine, Nicolas D’Aoust’s first wife) states that Claude is a farmer from Liesse married to Marie Wattelet.
This Claude Aubert is therefore the brother of Guillaume
(Guillaume Daoust's maternal grandfather). He is his great uncle!
