Thorstein Pederson Braaten

Hello. You GREATLY helped me a few years ago when I was researching my husband's great great grandparents (and others). Thank you for that. Well...I am back into researching again. My husband and I will be visiting Norway at the end of August so I was going to try to find more information. First question. I need a refresher on where to find information. I want to find the father and mother of Tosten Pedersen Braaten born Nov. 16, 1812 in Asnes. Also, the father and mother of Lisabet Torrisdatter Knappum born 4 Sept 1819 in Asnes. Tosten and Lisabet were married 3 Sept 1843. Thanks for any help Barb
