Marthe Jonsdatter, wife of Marcus Giermundsen

[MarkShepherd]

Marcus Giermundsen and Marthe Jonsdatter were married 30 Oct 1742 see http://www.arkivverket.no/URN:kb_read?idx_kildeid=7442&uid=ny&idx_side=-117. Does anyone have any information about Marthe's burial so that a birth year could be calculated? She likely died sometime after the birth of their child Lars who was christened 17 Sep 1747 and before Marcus marraige to Olie Pedersdatter in 1753, but I do not see any record of her burial in the Borge parish register. I assume she was born before Borge christening records were started in 1723, so there is likely not a christening record
