Surname Info (“Sukunimi-info” in Finnish) consists of 7940 family names found in Finland. Learn interesting facts about Finnish surnames (sukunimi), covering both Finnish-speaking and Swedish-speaking Finns. More details are available in Finnish. These pages have been created programmatically from publich databases, statistics and research publications. They cover all last names used by 100 or more Finnish citizens in 2014. Several less common last names are included too. The articles also list many rare names, although not the rarest ones. If a name is missing, it is not common in Finland. The information is all about names; you cannot find genealogic information here. The site is a summary of existing data, not a genealogical report on individual families.
