These were usually patronymics (the father's name with the suffixes '-sen' for a son and '-datter' for a daughter) until laws regarding inherited surnames were introduced in the C19th. Names ending in '-sson' or 'son' are likely to be of Swedish origin. During the late C18th, it was not considered fashionable to have a Danish surname and the aristocracy tended to change to French or German forms or spellings, some of which are retained.
