Norwegian Last Names

My family from Norway have very different names than those from England. Every time a father would have a son, that child would take their father's name and add 'sen' or 'son' to it (like Anfind Pedersen was Peder Anfindsen's son). Or, if he would have a daughter, she would take his name and add 'datter' or 'dotter' at the end of it (like Martha Guttormsdotter was Gutorm Sigurdson's daughter). Is this common throughout Norway, or was it just a family tradition?
