Here is the 1855 Norway Census for Ole Olson, before they moved to the Finnestad farm in 1863. Living at Skaareflaaden on the Nord-Skaar farm in Fister, Number 22 on the right side lists Ole Olson Søndenå at line 6, followed by wife Mari Iversdatter and daughters Elizabeth, Sarah, Iverdine, Bertha and Rachel. The last line (#13) isn't legible but looks like Magda Iversdatter (birth/farm name illegible). This might be her aunt; sister to Mari's father, Iver Reierson.
