Hi Tommy,
I am H1f from the U.S., but my paternal ancestors were from Finland (Oulu laani). The northern border of Sweden moved in recent centuries. Most people in northern Sweden were actually Finns as recently as the Finnish War of 1809. So, people in northern Sweden and many other areas of Sweden now have Finnish DNA. Going farther back to the 9th century, the people in most of the area of today's Sweden were from the early Finno-Ugric tribes. Refer to this map of early northern European tribal regions: https://commons.wikimedia.org/w/index.php?curid=54250790
Good luck with your research.
