Thina Olea Pedersdatter 1869 Bjørnskinn, Nordland

Having trouble digging up any more specific information on Thina than the fact she was born in 1869 in Bjørnskinn, Nordland. Her parents are Peder Nielsen (1818-1889, born in Lovik, Nordland, buried at Bjørnskinn, Nordland) and Berith Elea Faltinsdatter (b.03 Jul 1840 in Sellevoll, Nordland, Norway, baptized in Dverberg, Nordland on Aug 9 1840, death date unknown). I have combed through the same parish registers as her siblings, but am coming up dry. Siblings are: Pauline (1863-1850), Celius (1866-1944), Valentine (1968-1891), Petrine (1871-1944), Tollef (1874-1958), Online (1877-1924) and Fredrik (1880-1900). Most of the children were born in either Bø, Andøya, Nordland, Norge or Bjørnskinn, Nordland. Any help is appreciated. Here are the parish registers tried: Andenes, Bjørnskinn, Bø, Dverberg, and Sortland. Here is the link for the 1875 Telling for 1872 Dverberg. This is about as far as I've been able to get with Thina. http://gda.arkivverket.no/cgi-win/webcens.exe?slag=visbase&sidenr=1&filnamn=f71872&gardpostnr=89&personpostnr=660&merk=660#ovre
