·               Over 2,000 Scandinavian place-names are found throughout the former Danelaw area, chiefly in Yorkshire, Lincolnshire, and the East Midlands

·               The distribution of Scandinavian family names – such as those that end in -son (Johnson, Henderson, Jackson...) – also shows a concentration throughout the Danelaw

·              In Yorkshire and north Lincolnshire, 60 percent of the names recorded in early Middle English sources are of Scandinavian origin

·               Over 600 place-names end in -by, the Old Norse word for 'farmstead' or 'town', as in Rugby and Grimsby (Grim's farm)

·               Many end in -thorpe 'village, outlying farm' (Althorp, Millthorpe)

·               Some end in -thwaite 'clearing' (Braithwaite, Applethwaite)

·               Others end in -toft 'homestead' (Lowestoft, and Sandtoft) 

·               A Scandinavian name does not always reflect an original Danish or Norwegian settlement.  A local Danish aristocracy sometimes imposed a Scandinavian name on an Anglo-Saxon community
