Sørensen
Sørensen is a Danish-Norwegian patronymic surname meaning "son of Søren" (given name equivalent of Severin). It is the eighth most common surname in Denmark, shared by about 2,3% of the population. 
Immigrants to English-speaking countries often changed the spelling to "Sorensen" or "Sorenson" in order to accommodate English orthographic rules. English-language media often similarly renders "Sørensen" it as either "Sorensen" or "Sorenson". A parallel form of similar origin is Severinsen.
