I have just started building my own family tree and while i was searching for info i got a hit in your post "Vastrand (Hansen) Family Search".
If i am correct it looks like: Magnhild Knudsdatter Myrebø (born 1832) and married to Johan Andreas Hansen Vasstrand (born 1837) also are my 2nd great grandmother and grandfather.
Johan Andreas Hansen Vasstrand parrents was: Hans Gundersen (father) and Karen Pedersdatter (mother).
According to the information i have found i actually believe that your Great Grandfather full name was: Knud Herman Johansen. He was the brother to: Johanne Mathilde Vasstrand, that was married to: Olaf Andreas Simonnæs (My Great Grandfather).
By the way occupation "Huseier og Bryggearbeider" means "House owner and Dock worker"
