Andrew and Carrie Knutson

I need some help with info on my great great grandparents. This is what I know. Anders Knutsen(Knudsen) was born November 14, 1835 in either Mykland or Arendal, Aust-Agder, Norway. I found an Anders Knudsen on the LDS site that lists his birth as Nov. 12, 1835 and the christening taking place in Mykland, Aust-Agder on December 13, 1835. It lists his parents as Knud Anderssen and Kari Tergjesdr. He immigrated in 1849, according to the 1900 and 1910 US censuses and I found him arriving in New York on the Juno from Arendal, on August 18, 1849. I believe that he sailed with his mother and sister, plus his mother's brother's family. I found Karen Terjesdotter, age 34, but no Knud Anderssen. Just before her on the list is Svend Tergeson, age 27, along with 2 children and his wife. Anders is listed as being 13 and his sister, Guneld Knudsdotter is 15. He married Carrie/Caroline/Karen/Katherine, last name unknown, abt 1857 in the states. She is listed as being born in January 1, 1840 in Hitterdal, Norway. Thanks to Hopkins, I know that the current name of Hitterdal is Heddal, in Telemark, Norway. They settled in Waupaca County, Wisconsin and went on to have 17children. They are both buried in Park Cemetery, St. Lawrence Township, Waupaca County, Wisconsin. Carrie died October 12, 1929 and Andrew, October 20, 1931. At least I have longevity on this side of my family.[:)] She was almost 90 and he was close to 100! I can't find records for 1835 in Mykland parish and was wondering if someone could help. I'm trying to find out Carrie's family name or her parents names, but so far nothing. I want to find out if the Anders Knudsen the LDS site lists, is "my" Anders Knutson. There records are off by two days and I have his birthday from his tombstone. Thanks in advance for the help. Take care, Wanda
