The Vikings were a Norse people who, between the 8th and 11th century, traded with and plundered much of Europe, as well as parts of Asia and North Africa.
A lot of misconceptions exist regarding Vikings, most famously the supposed fact they wore horned helmets, which they didn’t. But even their culture ranges from savage barbarians to more civilized humans across different perceptions.
Talking about the Vikings names, Vikings compared to many people from the contemporary times did not use the previous name; instead they refer to people since the son of daughter of rather than a true name. This is why all of the names end in boy (son of) or (daughter of). For example, this is exactly the same as the kid in the modern names as Michaelson.
