Gregory of Tours
The connection between Amalaric and Athanagild and Leuvegild is not mentioned the authoratative "History of the Goths" by Wolfram. However it appears a dozen times in ancestry.com.
Gregory of Tours states Athangild and Leuvegild were brothers and Leuvegild married Athanagild's widow Goiswinth.
