Because specifically Offerdal and a village called Söderåsen are mentioned in those articles, we've been curious about this for a while," Sara Swedenmark, chair of the Offerdal Community Association, told The Local. When Swift decided to launch her Eras Tour in Sweden (she kicked the Europe leg of her tour off in Stockholm last year), the group decided to look into her possible connection with Offerdal, which is mentioned on several American genealogy sites, but always without reference to a source. "Offerdal in the 17th century was an uneasy place, because Jämtland was being torn between the Swedish king and the Danish-Norwegian king," explained Swedenmark.
