It certainly could be the right Martin. Some of the facts fit and others don't. I have Martin's father as Hans and mother as Nettie. The birth date I have for Martin is 2 April 1871 in Norway. I believe this is from Martin's death record. I don't know anything about Martin's siblings. I suppose one of the only ways to tell is getting an obituary on Hans. I wonder where the family came from in Norway. Thanks for pointing this family out.
