Origins of surname
Although undoubtedly of French origin - there are 27,000 records in the Geneanet database - this name seems to have escaped the attention of all our regular sources for the origin of French surnames. Jersey records suggest that it was used in the 15th century as a baptismal name.
The name first appears in Jersey church records in 1555, when Thomas Poingdestre, alias Cosnard, married Marie Gruchy in St Saviour, followed by the baptism of their son Thomas the following year, but there is then a gap until the next baptism in St Helier in 1700.
There were five Cosnard entries in the Grouville burial register during the 17th century.
The family seems to have died out in the island by the mid-19th century.
Some of the variants listed in our Comprehensive list of Jersey surnames date back to the 15th and 14th centuries. There does not appear to be a connection between the Cosnard and Cosnet families in Jersey church registers.
