Group A runes were most common in Viking Age Denmark
Old Norse Káti (m.)
Káti is a fairly common male personal name in the Viking world, occurring in the inscriptions on at least six Swedish rune-stones. It is the first element in the place-name Caythorpe, Nottinghamshire. There are also several place-names in Lincolnshire which contain this name, including Cadeby and Caythorpe. The name may originally have been a nickname, as it means ‘the cheerful one’.
