Ole Gundersen & Eli Mortensdatter

I am searching for the parents and more of Ole & Eli. Here's what I know. They had 2 sons, Morten born May 2, 1847 and Gulbrand born March 17, 1842. Ole & Eli were married in 1841. Ole was born in 1817 as far as I know and Eli was born in 1816 as far as I know. The lived in Trostagerlokken and Odlaugbraaten. I have Ole's father listed as Gunder and Eli's as Morten. I would appreciate any help I can get on this.
