Many of the Nylund's lived in the Ostrobothnia region of Finland. You may wish to consult the Genealogical Society of Finland for more information; they are on the World Wide Web and are very helpful. Some of your ancestors probably lived in Kvevlax. For example, Jacob Jacobsson Nylund married Maria Beata Jonasdotter Hjort in Kvevlax on 8 December 1844. My great grandfather was born in Kvevlax on 19 December 1869 and came to the U.S. in 1889. His name was originally Alfred Anders Johansson Svarvar, but he changed his last name to Nylund. He likely knew some of the Nylund's who lived in Kvevlax. Interestingly, his oldest son, Oscar (born 18 May 1894 in Hancock, Michigan; died 2 September 1936 in Portsmouth, Ohio), married Josephine Boutin, who was born either in Hibbing or Chisholm, Minnesota, in 1900 or 1903 (I haven't been able to confirm the date).
