The surname "Lyall" is found early in Scotland and was derived from the Old Norse given name "Liulfr" meaning Wolf.
 After the Viking settlement in Scotland name sounds would have changed.
 For example, "Liulfr" is pronounced 'lee-oolv-ur', but after time probably softened in pronunciation to 'lee-ooler' and then 'loo-il' and finally 'lyall' after the Old Norse "R" was dropped off the end.
 The Lyall Clan is a Sept of Clan Sinclair a Highland Scottish clan of Norman origin a people descended from Norse Vikings who held lands in the north of Scotland, the Orkney Islands, and the Lothians.
Battle of Bauds was a battle fought in 962 in an area known as the Bauds, south of Findochty and West of Cullen near Portknockie, Scotland between Scotland under king Indulf, and Norse pirates.
 The Vikings had been raiding and burning through Scotland, and had won numerous victorious skirmishes against the Scots, including the Battle of Dollar.
 However, in this battle, the Norsemen were defeated.
 Afterwards, Norse control in Scotland fell apart.
 However, Indulf was killed in the battle.
The Battle of Tara was fought between the Gaelic Irish of Meath, led by Máel Sechnaill mac Domnaill, and the Norse Vikings of Dublin, led by Amlaíb Cuarán.
 It took place near the Hill of Tara in Ireland in the year 980.
 The battle was a devastating defeat for the Vikings and led to the Irish regaining control of Dublin.
Amlaíb mac Sitric ("c".
 927981; Old Norse: Óláfr Sigtryggsson), commonly called Amlaíb Cuarán, in Old Norse: Óláfr kváran, was a 10th-century Norse-Gael who was King of Northumbria and Dublin.
 His byname, "cuarán", is usually translated as "sandal".
 His name appears in a variety of anglicized forms, including Olaf Cuaran and Olaf Sihtricson, particularly in relation to his short-lived rule in York.
 He was the last of the Uí Ímair to play a major part in the politics of the British Isles.
Ray is an English, Scottish Gaelic, and French name of Norman origin.
 This family name originated from the Normans, the descendants of Norse Vikings from Denmark, Norway and Iceland who later migrated to Normandy.
 This surname comes from the Old French word "rey" or "roi", meaning "king".
 It also derived from the same source of the surname Roy.
 Occasionally this was used as a personal name.
 The Normans brought this surname to England, which in medieval times was used as a nickname either for one who behaved in a regal fashion, or who had earned the title in some contest of skill.

The Battle of Islandbridge, also called the Battle of Áth Cliath, took place on 14 September 919, between a coalition of native Irish, led by Niall Glúndub, overking of the Northern Uí Néill and High King of Ireland, and the Dublin-based Vikings of the Uí Ímair, led by Sitric Cáech.
 It was one in a series of battles initiated by the native Irish to attempt to drive the Vikings of the Uí Ímair from Ireland.
 The battle was a decisive victory for Sitric Cáech and the Uí Ímair, with Niall Glúndub and five other Irish kings dying in the battle.
Vinland, Vineland or Winland (Old Norse: "Vínland" ) is the area of coastal North America explored by Norse Vikings, where Leif Erikson first landed in c. 1000, approximately five centuries prior to the voyages of Christopher Columbus and John Cabot.
 "Vinland" was the name given to North America as far as it was explored by the Vikings, presumably including both Newfoundland and the Gulf of Saint Lawrence as far as northeastern New Brunswick (where the eponymous grapevines are found).
The First Viking Age in Ireland began in 795, when Vikings began carrying out hit-and-run raids on Gaelic Irish coastal settlements.
 Over the following decades the raiding parties became bigger and better organized; inland settlements were targeted as well as coastal ones; and the raiders built naval encampments known as longphorts to allow them to remain in Ireland throughout the winter.
 In the mid 9th century, Viking leader Turgeis or "Thorgest" founded a stronghold at Dublin, plundered Leinster and Meath, and raided other parts of Ireland.
 He was killed by the High King, Máel Sechnaill mac Máele Ruanaid, which was followed by several Irish victories against the Vikings and the seizure of Dublin in 849.
 Shortly after, a new group of Vikings known as the Dubgaill ("dark foreigners") came to Ireland and clashed with the earlier Viking settlers, now called the Finngaill ("fair foreigners").
 The wavering fortunes of these three groups and their shifting alliances, together with the shortcomings of contemporary records and the inaccuracy of later accounts, make this period one of the most complicated and least understood in the fledgling city's history.
 In 853 a Viking warlord called Amlaíb (, possibly Olaf the White) arrived and made himself king of Dublin.
 He ruled along with his brothers Ímar ("Ívarr", possibly Ivar the Boneless) and Auisle ("Ásl").
 For the next fifteen years or so, they used Dublin as their base for a series of campaigns against Irish kingdoms.
 During these conflicts they briefly allied themselves with several Irish kings.
 The Dublin Vikings also carried out a number of raids in Britain at this time.
 The deaths of Ivar (c.873) and Olaf (c.874) were followed by internecine conflict among the Vikings.
 Although intermittent warfare between the Vikings and the Irish continued, these inner conflicts weakened the Viking colonies and made it easier for the Irish to unite against them.
 In 902, Cerball mac Muirecáin, king of Leinster, and Máel Findia mac Flannacáin, king of Brega, launched a two-pronged attack on Dublin and drove the Vikings from the city.
 However, in 914 the Vikings now known as the Uí Ímair (House of Ivar) would return to Ireland, marking the beginning of the Second Viking Age.
Sitric Cáech, also known as Sitric Gále, (Old Norse: "Sigtryggr" , died 927) was a Viking leader who ruled Dublin and then Viking Northumbria in the early 10th century.
 He was a grandson of Ímar and a member of the Uí Ímair.
 Sitric was most probably among those Vikings expelled from Dublin in 902, whereafter he may have ruled territory in the eastern Danelaw in England.
 In 917, he and his kinsman Ragnall ua Ímair sailed separate fleets to Ireland where they won several battles against local kings.
 Sitric successfully recaptured Dublin and established himself as king, while Ragnall returned to England to become King of Northumbria.
 In 919, Sitric won a victory at the Battle of Islandbridge over a coalition of local Irish kings who aimed to expel the Uí Ímair from Ireland.
 Six Irish kings were killed in the battle, including Niall Glúndub, overking of the Northern Uí Néill and High King of Ireland.
