I don'know if you have got any more information here?
I live in Haavik, Mosterhamn.
In the local history book I find your grandparents:
Here it stands that Kjolv was born in1853 to Bertel Kjolvson Eikeland born 1826-d.1864 and Brynhild Sorensdatter Anglevik born 1820-d.1893. Kjolv married Maren Sveinsdatter Haavik ytre, Mosterhamn.
Her parents were Svein Sveinson Haavik and MAlene Akselsdatter Skimmeland. Svein lived in Tysver for a while but came back to Haavik about 1864 and baught the farm from his brother.
There is more information about the family in the book if you want it.
You can also go to the Norwegian "Digitalarkivet" Here you will find censuses from 1801, 1865 and 1901 and also emigrant protocolls. I think most families from Mosterhamn went over Bergen habour.
You will also find old chuch parish records.
All this are for free.
