Sorry I haven't had time to do this for a while and didn't see your post. I will share what little I know. Christian "Miller"(sanpete nickname) Anderson and his wife, Rica are buried in Payson, Utah. I believe Peter Christian is buried in Spanish Fork. The family of "Miller" relocated to Carbon county before 1904, when a child was born there. (Ernest C. Anderson 12/07/1904). The family had ten children. One of them is buried in Mt. Pleasant (Arnold Gotheal Anderson b. 12/18/1896 Spring City, Utah. d; 5/17/1962 Mt. Pleasant). "Miller" and Rica Madsen were married in 1884 in Spring City. This is about all of the info I have, except the names of Peter Christian's brothers and sisters....
It is quite possible that the spellings are not correct.
Peter Christian's children are: Vera, Howard C. and Mabel
Hope this is of some help.
