Looking for info. on the RONNING Family

I believe that their name could have been spelled RONNINGSGRIND. I think that their Family farm was in Trondheim. Hans Toresen RONNING was married to Karen Olsdrotter (Sundlisaeter) Ronning. I think Hans was born in 1835 in Verdalen. Karen was born in 1835, I don't know where. I think that they had five Children. I would like to know more info. on Hans and Karen. When they were married and where. I would also like to know about their Parents. If anyone could help me I would appreciate it. Thank you!
