Looking for Forland relatives (Thomason)

My great grandfather Mons Thomassen Forland left Norway in 1900, leaving behind his parents and 8 siblings. He was the youngest, being born in 1877. His parents names were Thomas Larsen and Oline Monsdatter. His siblings were: Agathe = May 6, 1859. Dorthe = January 6, 1861 Anne Monsine = January 22, 1863 Lars = December 29, 1864 Oline = February 1, 1867 Abraham Olai = April 19, 1869 Peder Andreas = 1871 Gyri Malene = March 6, 1875 I also know that Lars had a child around 1900 in Forland that he named Thomas. I have a christmas card dated 1920 from Thomas and Ella to Uncle Mons. I presume this Thomas is the son of Lars and the nephew of my great grandfather. Does anyone by any chance have further information on any potential descendants still living in the area or know of any way to get in touch with the people over there in Forland?
