I have not heard anyone speaking of a person by the name of Hanne Pedersen Nielsen from Taars. I do have some men in my family that were born in Taars, but if you don't have any names to go on, that won't be much help. I don't remember anyone speaking of a man in New Zealand as they stayed in Denmark. If you have dates, I may be able to direct you to a website for censuses. I have found info on census yr. 1921 and earlier. If you have a birth date for Hanne or even your grandfather, you might find something. Let me know.
