Rise family, Strandebarm

I'm trying to locate living relatives in Norway, and can only trace them until the late 1800's in Strandebarm. My great grandfather was Kristoffer Olsen Rise born April 6th, 1886. Kristoffer had 3 sisters and 5 brothers the best I can tell. His brothers were Lars, Hans, Torger, Engel, and Ole if my information is correct. Also for water reason Kristoffer changed his name to Christ O. Rice after immigrating? I was also wondering if anyone knows how to get a map of farm/property numbers. It looks like they lived at Residence 39, Farm No. 48, Property No. 4 during the census I found this information on. Any help would be great!
