Hi Tammi, I just surfed Familysearch, and there I found Gertrud's parents marriage-date just the same as your on the Q:
Olof PALSSON
Spouse: Brita ENGELBRECTSDR
Marriage: 26 Dec 1746 Ytterhogdal, Jamtland
I searched for their birthdates, I found Brita:
Brijta ENGELBREKTSSON
Christening: 20 Jan 1707 Ytterhogdal, Jamtland
Father: Engelbrecht OLOFSON Mother: Kerstin ANDERSDR
For Olof no matches but two that are possibbel:
one Plof Pålson born 2 Feb 1720 and the other born 23 Mar 1722 -with Ytterhogdal as parish.
Are you sure that he came from Ytterhogdal?
