Where is Sande I Jarlesberg, Norway?

Hi, I am in the process of making a Heritage Book for my dad's side of the family. My dad's name was Per Martin Ruud. His parents came from Norway. My dad's dad was Edward Ruud and his mom was Margaret (Marguerite) (Margrethe) Caroline Ruud. Her maiden name was Sjol and her first marriage sur name was Weltsin. Her first husband died. I have a birth certificate for my dad that says the birthplace of Edward and Margaret was Sande I Jarlesberg, Norway. I also have an account written by my grandmother that says she left Vestfold and came to Canada on the Bergensfford steam ship in 1918. My grandmother Margaret came over with her nephew, Sigurd Salvesen. She married my grandfather, Edward in Canda and she was his second wife. His first wife was Margaret's sister and she died. Could someone please tell me where Sande I Jarlesberg, Norway is? Is there anyway that I could find the farm that they lived on or any direct descendents? Thank you for your time and for answering my questions. Jean Watt, Vermilion, Alberta, Canada
