Gea Poulsdatter

I am hoping to find any information on Gea Poulsdatter, including her parentage, siblings, spouse or children. The information I have indictes Gea was born 24 May 1864, mother was Gidsken Tollefsdatter. Gidsken was born 30 August 1838 in Godalen, may have resided in Røseplads, Grinden øvre, or on Bratten farm, Tolgen, Nordre Østerdalen (I think). I have no information on Gea's father and I am hoping for some help. Gea's spouse may have been Jon Johnsen (born about 1864), this very vague information is all I have, and I thank you for any insight or assistance you might be able to provide.
