Women should take their husband's name

The problem I see with this article is it takes too Anglocentric of an analysis. Sure, in English countries the tradition is for a woman to take the husband's name upon marriage. But plenty of countries--and yes, Christian countries at that--have longstanding practices of the wife not taking their husband's name, like Spain, Italy, and Iceland. In addition, the children in some of those don't just take the father's surname. In Spain a child takes the surname of both parents (people normally have two surnames in that country; their first surname comes from their father, and the second from their mother), and in Iceland people's surnames usually entirely different from their parents, or even from their siblings, as the tradition is to take one of their parent's first name and attach -son to it for a boy and -dottir to it for a daughter (e.g. if someone named Stefan had a son and a daughter and they took the surname from him, the son's surname would be Stefansson and the daughter's surname would be Stefansdottir).

It thus seems to incorrectly assume that a woman taking her husband's surname was a practice everywhere in Christendom when it wasn't. Heck, from a little (admittedly cursory) research, it seems like surnames themselves only started getting popular in Western Europe after the 10th century AD and didn't become universal until much later.
