History/Origins of "Kristenhaugen"

Hello all, I'm working on locating a record in Norway of the "Kristenhaugen" family prior to their emigration. Facts that I have thus far: From a 1934 intensely-researched history (Americanization of many names here, I'm sure): "Well at any rate years passed by and finally we find an old gentleman making his way northward from Christiania or Oslo as it is now known, in a small fishing vessel. He finally landed in that territory around Gjovik and Odnæs and settled down. And there we get into 'our first actual history of the Haugens. You all know, or maybe you don't—that your name really isn't Haugen at all...It's KRISTENHAUGEN—believe it or not. The name was changed later on so we have something to be thankful for after all. It was Kristian Kristenhaugen who was the father of the Haugens we known—our grandfather one whom we never saw but who we all know was a man of sterling character and highest integrity. He was married to Karen Kinseth, a fine woman, who spared no efforts to bring her children up in the best possible manner and to impress on them that they should always be God fearing men and women and do only what was right." Considering that "Kinseth" was likely "Kindsæth" and a farm name, is it possible based on Norwegian name structure that this record might be them?: 1. Karen LASSESDR - Vital Records Index - Norway Gender: <F> Birth: <1829> Marriage:18 May 1853 Place: Sund, Hordaland, Norway [Remove] 2. Christian HAAGENSEN - Vital Records Index - Norway Gender: <M> Birth: <1826> Marriage:18 May 1853 Place: Sund, Hordaland, Norway Karen and Christian's eldest daughter, Martha L. was born abt. 1856. I've been working on learning name structures back then, to be able to ascertain how "Kristenhaugen" in its original form may have evolved into "Haugen", which is the name which they all used when they emigrated. All of the male children adopted the middle initial "C" when they came to America, as the first initial of their father's name "Christian". Any help that you can provide will be appreciated. I have enjoyed reading many of your postings related to names. Warm regards, and thank you all for the wonderful ongoing education that this site represents.
