Martine Petersen

Hi All, I found a baptismal record for my G-Grandmother Emma Kristine Petersen in Vega, Nordland in 1884 http://www.arkivverket.no/URN:kb_read?idx_kildeid=2544&idxid=2544&uid=ny&idx_side=-115 also there is her marriage record there as well in 1908 IIRC. The Baptismal record lists her parents as Martinius Petersen and Martine Petersen I think I may have found applicable cencus records for Martinius in the 1865 record. but am lost on Martine. any help would be appreciated.
