Anders Hansen (Ihle)

Hello to all I am looking for info on a Anders Hansen Ihle not sure where the name Ihle came from. Anders was born Norway 1833 and married Marthe Peders. They had 2 children Hans 1867 and Jorgine Dina born 1869 in Nord Odal Hedmark. They emigrated to New Zealand between 1869-71 as their next child was born 1871 in NZ. Their surname in New Zealand was Hansen which with your naming patterns the children should have been Anderson/dtr Any info will be great Shirley
