Pousette is a Swedish family name of Walloon origin.
Pousette is one of Sweden's largest Walloon families and the name was originally written Poncet.
The family has a strong connection to the forges in northern Uppland, where the family members worked mainly during the first century after arriving in Sweden in the 1620s.
Ancestors of the family are the brothers Gottfrid and Martin Pousette who signed contracts in Liège in eastern Belgium in 1627 and from 1629 worked at Lövsta forge.
[1] In the Swedish family calendars of 1963 and 1974, the Gävle branch of the family is said to have originated from the wholesaler and shipowner Johan Fredrik Pousette (1816–1880).
