Kings of Dublin

In the chronicles the seaborne warriors who took over Dublin are usually referred to as “Ostmen,” men from the east, or as “Danes,” although most of them were Norse.

As is very common throughout the world, in both the Norse and Irish cultures a person's surname was formed from the name of his father. For example, among the Vikings Ivar's son Olaf would be Olaf Ivarsson.  Among the Irish, paternity was indicated by the prefix “mac,”  so for example Murchad the son of Diarmuid would be Murchad mac Diarmata.  Applying the Irish usage (as the Irish did) to Norse names leads to some interesting connections betwen modern surnames. In Irish, the Norse Olaf (or Olav) becomes Aulaffe, and Olafsson (Olsen) becomes Macaullife.   Ivorsson (Iversen) = Macgyver; and so on.

Either form of a name may be encountered in histories, depending upon the perspective of the writer. As an aid to recognizing the names, the Norse form is given first, followed by the Irish in curly brackets.

Many of the dates are approximate.
