Interesting names in Sweden

I want to know where I may find an explanation for the following place
names:

Kvämmir-Batsin (a lake in a wood in central Sweden, a few miles from
the norwegian border)

Sigri-Lotsin (a marshland in the same area as the lake above)

Kvänn-Tölln (same kind of marshland)

Sjigir-Kneippa (woodland to the south of the above named places)

Vein (another woodland)

The reason for putting this on cybalist is because I believe there is
some indoeuropean elements in these names but I have yet to identify
any of them. Can you help or show me where I might find help?
