Ottum/Hustad lines

Hello, I'm new on here. I am a descendent from the area of Luster County. My grandparents were 2nd generation from Norway. Olaus Johnson Ottum aka Olaus "J" Ottum and Thea Olava Hustad. My dad did a lot of genealogy and I have a huge chart which he transcribed the information from Luster County History (5 volumes) by Lars Oyane. I would love to hook up with someone who knows this genealogy and could share things with me. I am totally confused by the records and don't really know where to go. I'd also like to fill in other lines and get stories and pictures, etc. instead of just names on a chart. Some of the other names on my chart are Lerum, Kilen, Svenstraedet, Notevsa (Eric Ellingson Notevsa actually. I have one transcribed record about him in my files. My grandparents grew up and lived in Buffalo County Wisconsin. Thanks for any replies:-) Marsha Ottum Owen
