Haneholmen does not give any results on any of the Norwegian maps.

The digital reference mentions a place called "Skjæggestø", in modern norwegian written as "Skjeggestø".

This place is on the map east of Kilsund.

Nærby is a small island called "Store Havneholmen" (and at the same time called Skjeggestøholmen). Only one letter difference...

Needs further study.
