Farsund family

I am trying to find out how to get a birth certificate for my father who was born in Norway. He was raised on the Farsund farm in Fjorde Norway. I believe his father was Ludvig Tollevsen Farsund. Also is there any way to find out mailing addresses or email addresses of people in Norway. I was in contact with my uncles grand daughter, Linda Evebo until about 2 years ago but havent heard from her in a long time. I think I do have relatives still in Norway but it is difficult to communicate cause they dont speak English ( except Linda Evebo does) Any help would be appreciated. Thank you Linda
