Danish Surname Generator

Danish surnames are even more patronymic-heavy than the rest of Scandinavia: Nielsen, Jensen, Hansen, Pedersen and Andersen — all '-sen' names — together cover a large share of the population. A 1828 law froze these patronymics into hereditary family names.

About Danish surnames

Nielsen, Jensen, Hansen, Pedersen and Andersen are the five most common Danish surnames.
'-sen' = 'son of': Nielsen = 'son of Niels'.
Because the patronymic stock is so small, many Danes also use a place or farm name (Vestergaard, Nørgaard, Holm).
Spelling varies: Nielsen / Nilsen / Nilsson across Denmark, Norway and Sweden.
