Elsie, where did you find the connection to Bohuslän? Was Hanna born there?
Borås is in Västergötland, not in Bohuslän.
The administrative region for both areas is nowadays called Västra Götaland. Earlier, Borås belonged to Älvsborgs län and all of Bohuslän belonged to Göteborgs och Bohus län.
If your friend is sure of the birth and death years these people could be the family you look for. According to the Swedish Death Index:
