Svinhufvud
Svinhufvud (, literally translated as " Swine head" or "Boar's Head") is a family of ancient Swedish nobility originating from Dalarna. The family is incorporated both at the Swedish House of Nobility and the Finnish House of Nobility.
A prominent member is Pehr Evind Svinhufvud, President of Finland from 1931-37. Prince Daniel, Duke of Västergötland (né Daniel Westling), the husband of Victoria, Crown Princess of Sweden, shares ancestors very far back in time with this family.
The first known ancestor of the Svinhufvud family is Jöns Swinshwow (modern spelling: svins huv') who lived c.a. 1340-1420.
