The history of the last name Casnave

The surname Casnave has its origins in the Basque region, which straddles the border between Spain and France. The name likely emerged in the latter part of the medieval period, around the 13th or 14th century.

The name Casnave is believed to be derived from the Basque words "caña" meaning "reed" and "nava" meaning "flat land" or "plain". This suggests that the surname may have originated as a place name or descriptive name for someone who lived near a reed-covered plain or marshland.

One of the earliest recorded instances of the surname Casnave can be found in the archives of the town of Saint-Jean-Pied-de-Port, a commune in the French Basque Country. A document from the year 1476 mentions a certain Jean de Casnave, who was likely a landowner or prominent figure in the area.

In the 16th century, the Casnave name appears in several Spanish records, including the baptismal records of the church of San Sebastián in the Basque city of San Sebastián. One notable entry from 1587 records the baptism of a child named María Casnave.

During the 17th century, a branch of the Casnave family settled in the region of Labastide-Murat in the French department of Lot. Here, they became known as the "Sieurs de Casnave", indicating their status as minor nobility or landowners. In 1672, a certain Pierre de Casnave was recorded as the lord of the manor of Labastide-Murat.

A famous bearer of the Casnave name was Jacques de Casnave (1708-1784), a French military officer who served in the War of the Austrian Succession and the Seven Years' War. He rose to the rank of Lieutenant-General and was appointed Governor of the city of Perpignan in 1778.

Another notable figure was Pedro Casnave (1795-1872), a Spanish-born merchant and landowner who settled in Uruguay in the early 19th century. He played a significant role in the development of the country's agricultural and livestock industries.

In the late 19th century, a Casnave family from the Basque region of Spain emigrated to the United States, settling in the state of Idaho. One member of this family, Juan Casnave (1865-1943), became a prominent figure in the local sheep farming industry.
