Wow, Richie! I'm really impressed at your Scandinavian research and your ability to translate them, however loosely. Much respect. I have all the easily accessible translations such as Jamieson, Borrow, Dal, Prior, Grey etc.

The sister version of Sven I Rosengard has implications for Lucy Wan and could possibly have suggested it. I have several translations of Sven in the books above if they are of any use. You obviously have Archer Taylor.
