Natt och Dag
However, the actual name Natt och Dag, alluding to the contrasting colours of its coat of arms, was not coined until the sixteenth century, and was not used as a surname by the family itself until the eighteenth century[1][2] It is therefore customary to write the name in parentheses (e.g. Bengt Stensson (Natt och Dag)) when applying it to individuals prior to 1700.The family's oldest known ancestor is the knight, Lawspeaker of Värend, and Councillor of the Realm Nils Sigridsson (Natt och Dag), who is first attested in a document from 11 May 1280 and lived at Ringshult, near Torpa in Östergötland.Gabriel Anrep, a Swedish genealogist, wrote in 1862:[3] That this family stems from Sigtrygg, a rich man, who, according to Sturlesson, in the year 1030 lived in Nerike and, during the winter, housed the Norwegian King Olaf Haraldsson the Holy, and that Sigtrygg's son Ivar thereafter became a distinguished man, may be true but lacks evidence.In the fifteenth century, the family split into two branches.The Younger Stures enjoyed great prominence in the late fifteenth and sixteenth centuries.[2] The other line descended from Måns Johansson produced a number of military officers in the seventeenth and eighteenth centuries, during Sweden's Great Power Era, and in more recent times the prominent governmental official Åke Natt och Dag [sv] and the writer Niklas Natt och Dag.
