Do you have a parish or city where Niels Peter Hansen was from? There are three "place names" or "farms" with Hollose. One in each of the following parishes and counties: Gunderslev, Soro County; Kvanlose, Holbaek County; or Vejby, Frederiksborg County. Many of the censuses aren't available online for 1890 or later, but I did find one possiblity:
Niels Peter Hansen, of Gunderslev Parish, Soro county:
on the 1880 census living with his family. His father's name is Hans Hansen. Niels Peter is 1 year old. Could this be a match? The source is the Danish Demographic Database on the internet.
