I'm writting a fiction novel and need help by someone Icelandic to make sure the names actually make sense.

The novels town has a harbour, and the volcanic caves/ mines.The town rebuilt by nine families on the cooled ashes, after eruption and floods had destroyed the original settlements. Name of town:

Muninnvik

Muniuvik

Daudavik ( dauthavik, Icelandic letter not on leyboard)

Draugrhofn

Surtrhofn

Surtrvik

Niuness

Another question. The surnames.. son, dottir. Protagonist is looking at the genealogy of families working out who could be from the original towns founding families. But like current resident Blikasson , wont definately be connected to Blikasson, lived 130years ago, or Helgadottir now not related to Helgadottir from 3 generations ago. The immigrant James Harper, who married Icelandic Anna Jonsdottir wont make her to Anna Harper, their child Eric can be called Eric Harper, daughter Liana Harper. Daughter Lianna married to local David Magnusson doesn't become Magnus but her child would be either Jon Harper or Jon Magnuson. How do you work out your genealogy and is there some archives I could dig in for examples?

Thanks!!!
