Trying to find information about Ida Melaas

Hi, I am trying to figure out information on a cousin of my great-grandmother's. Her name was Ida Melaas and as far as I know she was born in Norway but I am not sure what part. I found quite a bit of information about members of her family on a cemetary record on the internet. Her full name was Ida Cornelia (Caroline) Amalia Melaas and it says she was born to Ole Olson and Olava (Larson) Melaas. My great-grandmother's name before she was married was Martha Ensrud and her mother's maiden name was Melaas so I am assuming that Ida's father and Martha's mother were brother and sister (if Martha and Ida were first cousin's). the website I found says that the cemetary Ida is buried in is in Flom, Minnesota and that is where most of here siblings are buried as almost all of them did not get married. Previous help I've got from this forum found information that Martha's partents names were Peder Olsen and Karen Olsdatter. So it would make sense that Karen (Martha's mother) and Ole (Ida's father) were siblings as their last names make it sound like they had the same father. Any help would be appreciated on anything anyone can find! Tim Larson
