Birth Record Translation/name question

Hello, I'm hoping somebody might understand what this birth record says. It is the first entry on the second page, Maria. I am curious what Qvarterm is (this is in front of the father's name). Also, my families name seems to have been Gjertz and I am curious to know what type of name this is. I can't figure out where my ancestor Anders Olsen Gjertz was from but he seemed to move from farm to farm and was a Sheriff in Totens in the early 1800's. He lived ca. 1779-1819. (Fridrick Gjertz in this source record below that I need help translating is his brother). Source information: Oppland county, Toten, Parish register copy nr. 1 (1814-1820), Birth and baptism records 1817, page 42.
