The d'Aubert family, or Aubert, is a family of the French nobility. Branches also belong to the Nobility of Denmark and to the Nobility of Norway. The family originates in the town of Thionville in Lothringen (now the Lorraine region), where their progenitor Jean Aubert was a merchant. Today members live in France, in Denmark, in Norway, in Sweden, and in Germany.
The noble family of Aubert was founded in the Duchy of Lorraine with the ennoblement in 1612 of Jean Aubert, a merchant of Thionville. This town was at the time in Habsburg possession and a part of the Holy Roman Empire. In 1659 it was annexed by France.
Jean d'Aubert's great-great-grandson, François Jacques Xavier d'Aubert (1727–1793) emigrated to Denmark in 1752 to take up a career in the Danish army. He became a Dano-Norwegian nobleman in 1776.
Separate branches of the family descend from his two sons, both military men: Benoni d'Aubert (1768–1832), who moved from Denmark to Norway and founded the Norwegian branch of the family, and Jacques d'Aubert (1769–1844), whose son Oskar Aubert (1831-1900) was the ancestor of the Danish and German branches of the family.
