Hello Byrthnoth
If you are looking for warriors from 6th and 7th century Scandinavia the burial site Nørre Sandegård Vest on the island of Bornholm is the place to go. It’s the only Danish burial site with weapon graves from that period.
You can read about it in more detail here: Jørgensen, L. & Nørgård Jørgensen, A: Nørre Sandegård Vest. A Cemetery from the 6th-8th Centuries om Bornholm. Nordiske Fortidsminder , Serie B, vol 14. København 1997.
For a broader Scandinavian picture you can take: Jørgensen, Anne Nørgård: Regional Studies of the Weapon Burial Practice in Scandinavia, 530-800 AD. Medieval Europe vol. 4 York 1992.
These are archaeological texts, but they are in English, and they cover your periode.
Hope you find it usefull.
Cheers
Erik
