Group A runes were most common in Viking Age Denmark
Old Norse Gyða (f.)
Gyða appears early in Norway and is frequent there but it is not as common in Iceland. It appears in two Danish runic inscriptions and is common in other Danish sources. The name also appears in a few Swedish runic inscriptions and is found in later Swedish sources. Gyða is also attested in medieval documents from Lincolnshire and Domesday Book for Yorkshire.
The name is a pet form of Gyríðr and it has been suggested that it was borrowed from England because several of the oldest carriers of the name appear to be of mixed Nordic and English origin.
