Original: Sif does not respond, and the exchange turns to Beyla. Sif is additionally mentioned in two kennings found in poems collected in the Poetic Edda; HymiskviÃ a (where Thor is referred to as the "Husband of Sif" thrice), and Ã rymskviÃ a (where Thor is once referred to as "Husband of Sif").
Simplified: Thrud is the only daughter of Thor and Sif.
