the chronicle, Godred granted the incomers lands in the south of the island, and allowed the natives lands in the north, on the condition that they give up all heritable rights to this territory. It was through this act, alleges the chronicle, that Godred's later successors owned the entirety of the island. This portrayal of Godred's takeover—in which a conqueror establishes his dynasty's dominance over the traditional rights of a native landholding populace—parallels the traditional mediaeval accounts of Haraldr hárfagri, a king traditionally said to have deprived Norwegian landholders their heritable rights. Although several place names on Mann appear to date to the tenth- and eleventh-centuries, stemming from direct settlement from Norway or Norwegian colonies in Scotland and the Isles, many Manx place names that contain the Old Norse element - appear to have been coined by later settlers from Denmark or the Danelaw. Some of these settlers would have arrived on the island from the Danelaw in the tenth century, whilst others could have arrived in the course of Godred's conquest. In fact, as late as the sixteenth century some of the island's most considerable lands contained this word element. Further after-effects of Godred's conquest may perceptible by numismatic evidence. Almost twenty mediaeval silver hoards have been uncovered on Mann. Almost a dozen date between the 1030s and the 1070s. The finds seem to suggest that the island suffered from power struggles until the establishment of Godred and his descendants. Domination of Dublin and the Irish Sea The Annals of Tigernach and the Chronicle of Mann evidence Godred's conquest of the Kingdom of Dublin in about 1091. Specifically, the former source accords him the title "King of Dublin" that year, whilst the latter source claims that he subjugated all of Dublin and much of Leinster. Although the chronicle's statement regarding Leinster is almost certainly an exaggeration, it may well refer to the seizure of the full extent of Fine Gall, and the extension of royal authority over adjoining regions. Dublin's political affiliation at about this period in time is uncertain. In 1088, Donnchad mac Domnaill Remair, King of Leinster seems to have utilised troops from Dublin in his attack on Waterford. Whilst within the same year, troops from Dublin, Waterford, and Wexford were repulsed in an attack on Cork by the Uí Echach Mumain. The following year, Donnchad is further accorded the title , which suggests that he ruled
