Hans Olsen / Marit Østensdatter

I am searching for more information about my ancestors Hans Olsen (Kaggerud) and Marit Østensdatter. I have the following: Han's death Vågå / Vågå 1827 - 1842 Ministerialbok. page 149 record # 54. Marit's death Vågå / Vågå 1842 - 1856 Ministerialbok page 194 record # 1. Their betrothel Vågå 1739 - 1810 Ministerialbok page 114, 1st column # 10. I would like to find record of their births. According to the death records his should be about 1762 and hers about 1764. I can not seem to find them, maybe it is the language problem. Any help would be appreciated.
