But chronologically that is impossible unless either the genealogies in the Ynglinga saga or those of Hálf's lineage are incorrect or defective (or both are incorrect). The Hversu notes further that another son of Grjótgard was Sigar (Sigarr), father of a daughter Signýjar who married Jarl Harald of Naumu Dale who fathered on her Herlaug, father of Grjótgard, father of Jarl Hákon, father of Jarl Sigurd, father of Jarl Hákon of Hlada. (These last three were contemporaries to and supporters of King Harald Fairhair. Indeed, one of Harald's wives was Ása the daughter of Jarl Hákon son of Grjótgard. However the Herlaug who was king of Naumu Dale according to the account in Harald Fairhair's saga in the Heimskringla could certainly not be Jarl Hákon's grandfather.) Commentary The word garðr means 'an enclosed piece of land' and is cognate with English yard and garth. The element garðr is commonly an element in place names such as Asgard, Midgard, Micklegard (a common Norse name for Constantinople), Holmgard (a common Norse name for Novgorod), and so forth. So, though Garðr does appear as a man's name, it is possible that Garðr Agði is in origin a personification of the Land of Agdir, and that his sons whose names end in -gard (-garðr) are similar personifications of other regions of Norway, euhemerized into first kings of those regions. Thrym is otherwise known only as the name of a giant. See Thrym.
