transcription help for Telemark birth

Good morning! I am having a bit of trouble reading a a few words on a baptism and hope someone can give it a quick look. Here is the link, and the person is Isach born on Feb 22, 1784 on second column of page 54: http://www.arkivverket.no/URN:NBN:no-a1450-kb20061201010318.jpg I have the witnesses names, but the part I am having trouble reading is what is immediately following the father's name: "Gunder Olesen Gierstad (...?....) og (and) Marthe Torchelsdatter. Thanks for your help!
