looking for Torbiør Kolbensdatter in Hordaland

Hello everyone, I am looking for the mother of my g-g-grandfather, Anders Pedersen Berge from Voss, Hordaland; after the birth of her son Anders, I lose track of her. I am hoping that someone can help me find information on her life after 1819. Here is some background information: Her name was Torbiør Kolbensdatter, and if I am correct she was born 7 Nov 1777 http://www.arkivverket.no/URN:NBN:no-a1450-kb20070104610254.jpg Her parents were Kolben Pedersen Hommedal and Brita Larsdatter Lodveteig or Lødveteyen. It appears that Torbiør was illegitimate if I read the birth entry correctly. Peder (Per) Andersen was born in December (not sure of the date) and christened on 21 Dec 1791 in Voss. http://www.arkivverket.no/URN:NBN:no-a1450-kb20070524630224.jpg the son of Anders Knudsen Berge and Ragnhilde Andersdtr. Vaethe. Anders Knudsen Berge dies in 1806 and leaves his son Per the farm and as he had no brothers I assume that whatever property Anders had, he left to this son. How and when Peder Andersen met Torbiør Kolbensdatter is unknown. Torbiør and Peder have a child, Anders Pedersen Berge http://www.arkivverket.no/URN:NBN:no-a1450-kb20070524630631.jpg born out of wedlock, and one of the witnesses may or may not have been Torbiør’s father (shown as Colbein Berge). Peder marries two years later in 1721 and has 5 children. It is at the birth of Anders in 1819 that his mother Torbiør disappears from the records: I have not (yet) found any marriage for her, immigration (internal or external), or death records either. If someone could take a look at the information above and perhaps find some link to her life after this, I would really appreciate it. Thanks in advance! Kathy#8232; [Just an extra note: After the rather irregular and inauspicious beginning to his life, the first Anders Pedersen Berge leaves Norway in spring of 1844 to become one of the first Norwegian settlers in the Wisconsin territory. He probably did not regret the move to change his life: he was a successful farmer owning enough property that he was able to give three of his sons each a farm of 160 acres, and died at the age of 78.]
