Group A runes were most common in Viking Age Denmark
Old Norse Fótr (m.)
The male name Fótr is the name of a fairly prolific Swedish rune-carver and is found elsewhere in Scandinavia. In England, the name occurs in several place-names in Lincolnshire (Fotherby, Fosdyke and Foston) and possibly in another Foston in Derbyshire. In Fotherby, the place-name preserves the original Old Norse genitive singular ending (ie. as in Fótar). Such clear indications of Old Norse grammar survive relatively rarely in modern forms of place-names. Originally, Fótr was a by-name, meaning ‘foot’.
