I am looking for my grandfather's brother, Sigvard Antoni Andreassen/Hammer. He was born 12 Jun 1884 in Næroy, Nord-Trøndelag, Norway. He is in his father's house in the 1900 census, at which time he was a farm laborer and fisherman, and then at some point afterwards immigrated to Iceland, to Isafjord. I believe he had died by the time my grandfather died in 1967. His parents were Andreas Larsen and Anne Johanna Olausdotter Lassemo of Nærøy, on the Hundhammer farm. Some of his other siblings were: Anna (Stene), Johan "Alfred", Lars, Laura Myrhen, Ole, Oluf, Emma, Emil, and Adolph. Oluf, Emil and Adolph immigrated to the United States (South Dakota) and had been using the surname "Hammer" for at least five years prior to immigration.
Would appreciate hearing from anyone who might know of this man or his family, or who could advise me on where to go from here.
