Hi Janet
Found your message by accident and as I am from Skelleftea I thought that I could help you a bit. There is a local Genealogy Society but they only have swedish pages. This is the URL:
http://www.skelleftea.org/forening/fss/Searched and found this Swedish emigrant site, they might be able to help you (there is an english page):
http://www.emigrantregistret.s.se/index.htmlLet me know if you need further information. Do you know from which village or part of Skelleftea they came from?
Regards
Katarina
