Galswintha [SEP] father
Galswintha
Galswintha (540–568) was a queen consort of Neustria. She was the daughter of Athanagild, Visigothic king of Hispania (the Iberian Peninsula, comprising modern Spain and Portugal), and Goiswintha.

Galswintha was murdered at the urging of Chilperic's former wife, Fredegund, instigating a 40 year civil war within the Merovingian kingdom.
