Christoffersen Christoffersen (] ) is a Danish-Norwegian patronymic surname, literally meaning "son of Christoffer", the North Germanic form of the Greek given name Χριστόφορος, Christóphοros. There are two less common spelling variants Kristoffersen and Christophersen; they have identical pronunciation. In Denmark, the three spelling variants are the 53rd, 83rd, and 205th (respectively) most popular surnames. In Norway, "Kristoffersen" is the commoner form, but "Christoffersen" is also found. Occurrence of the surname outside Denmark, Norway and Schleswig-Holstein is due to migration. Immigrants to English-speaking countries sometimes changed the spelling to Christofferson, Kristofferson, or Christopherson.
