Descendants of Trgyve Goberg

I am the grandaughter of Trgyve and Louise Goberg who came to Canada in either 1919 or 1920 They were married in Skien Dec 6th 1919. My Mother (Edle Lillian) was born in Throne Alberta Canada November 19th 1920 I know My Grandfather had relatives still back in Norway as my parents Don and Lillian Prudden received letters from them. My parents are now deceased and my husband and I are coming to Norway this summer so it would be wonderful if there was a possibility in finding some relatives.. My Mother never got the chance to go to Norway so I am very excited to see the church in Skien where my Grandparents were married. Hoping someone can help me out. Valeen holland
