Lindsay,
Flo socken = Flo parish. It was in Skaraborgs län (county) at the time, which would be in Västergotland province. (Yes, it looks like Vestergöthland here. Spellings have changed over time.) Flo is now in Västra Götaland län. (Skaraborg, Älvsborg, and Göteborg och Bohus län were merged.) The place which you saw as Vintergothland was Vestergothland (Västergötland).
Look at these maps of Swedish län, both old and new.

http://tinyurl.com/yg7gbt Ekarebol is a place (Fideikommissegendom -- Perhaps the Swedes will define it. My dictionary calls it an entailed estate, whatever that means.) in Bolstad parish, according to the Rosenberg CD. They were living there when they decided to move out.
