Galswintha combines the Old German gail (song) and swind (strong). **Galswintha (c. 540-568)** was the Visigothic princess (sister of Brunhilda) sent to marry Chilperic I of the Franks — **murdered by her husband at the instigation of his mistress Fredegund**, triggering the bloody Frankish civil war that consumed two generations.
Featured in Gregory of Tours's Histories.
Galswintha reduces to four — the number of Visigothic princess.
