Birthe Oline Hansdatter (Tiesen)

I am looking for the Parents and ancestors of Birthe Oline Hansdatter (Tiesen). I read in a post on this site to me that Birthe is listed with the surname of Hansdatter except when listed with Lovise, her daughter. Her surmane then is Teisen. I also found both surnnames on familysearch.org. No parents seem to be listed for her anywhere I have looked. I have also seen the name Oline spelled Olene and Alene. Birthe married: Johan Martin Lohrbauer b. November 8, 1793 Vor Frelser, Oslo, Akershus, Norway m. BIRTHE OLINE HANSDATTER (TEISEN) b. 1798 children: Maren Charlotte Dorthea Lohrbauer, Caroline Christine, Lovise Benedite Johanne Lohrbauer, Johan Luvig Lohrbauer. Any help would be greatly appreciated. Thank you.
