According to the Emigranten database, the following family emigrated in 1874 May 1:
Anna Maria Ekberg, age 42
s.Per Johan, age 15
d. Anna, age 11
d. Emma, age 9
s. Frans, age 6
They all travelled through the port of Göteborg and all had tickets for Orion, no state listed.
The problem is the place they came from, which is listed as Gravared, OA county, which would mean a place in Göteborg och Bohus län, and I cannot find such a place in my gazetteer. There is a parish, named Grovare in Älvsborg county, which might be a possibility. Perhaps somebody else in this Forum knows better?
