Rasmus Hansen and Marie Anne Tolfsdatter

Hi, I'm searching the marriage record for my 2 ancestors. They lived all their life around Tune, Osfold Rasmus was born on April 26, 1795 in Bentemyr under Vister Sondre. Marie Anne was born in 1798 in Bentemyr under Vister Sondre They had a child on Dec 12th 1818, named Has Rasmussen. So I assume they were married before 1819. Marie Anne died in 1826. Thank you, Carl Savard Canada
