Hello and Welcome Hanna and Rodney:
I have been looking at the pictures you posted and the floor, from the pictures, the period, and what was used in our area; I would call the floor material tounge and groove pine. The porch picture has the same material showing. The pine floors were often used without any subfloor and simply toe nailed to the floor joists. If there is a subfloor under there, I would come nearer calling it tounge and groove oak. It is a little difficult to discern the wood grain from the pictures.
