The Anthon Marqvorsen who was born in Torslev in 1842 is definitely your ancestor. Now for my reasoning.
In the 1855 census there is only one person with a name close to Anthon Marqvorsen living in Torslev. A search of the tilgangliste for the period 1855-1864 shows no one else with a name similiar to Anthon coming into the parish. Therefor, your Anthon has to be the father of Petrine Jensen, since we know the father was living in Torslev at the time of the birth.
According to the afgangliste for Torslev, Anthon Marqvardsen, age 25 1/4 left Torslev for Gislum, Aalborg on 3 Jan 1868, opslag 71 nr 1.
