Re: Identifying Home - Victorian?
I'd call it a 1 3/4 story victorian cottage.
It may have been from a published plan.
The tin-covered hole in the floor was either a stovepipe brought through or a grille to the ceiling below, for the purpose of a little extra heat for the room.
That chair rail molding surrounded by drywall isn't original. It's a piece of crown molding installed flat. There could be an original molding under it, or not.
Remove not the ancient landmark, which your fathers have set.
