Early Origins of the Duchy family

The surname Duchy was first found in Dauphiny (French: Dauphiné or Dauphiné Viennois), a former province in southeastern France, where this prominent family was established in ancient times.

The family became even more prominent through contributions by its members to the society and to their respective communities, and also through many alliances with other important families of the day. An important alliance was formed between the branch Duquet and the Mercier family of St. Sulpice in Paris. The branch Duchat d'Aubigny was ennobled in Metz, Lorraine in 1721.

Denis Duquet, born in 1612, settled in Canada in the 17th century. After arriving in Quebec he married Catherine Gautier, born in 1627, on 13th May 1638. They had one son, Pierre Duquet, and he married Anne La Marre in Quebec on 23rd August 1666. 1
