How old is our home?

We moved into our first home this past year - a cozy and modest century home in NJ. We were told the house was at least as old as 1895, as this was the first record of it on a town map. Previous owners had the house surveyed by the state historical preservation office in the 90s. They found that the land was purchased in 1865 and some features of the home were consistent with the mid-19th century. This same report called the home’s style a Greek revival. Through my own brief research, some of the homes features seem more Italianate (eg the newel post). We were told the first owner was a builder who built the house for himself, so he possibly mixed styles?

I attached some photos of features of the house - hardware, exterior, original floors, built-in cabinet in dining room, bay window, a-frame roof in current kitchen, archway from living room to dining room (maybe not original?) etc. Unfortunately the fireplace has been covered behind a wall (we plan on looking into a possible restoration). It is in the middle of the house. All bedrooms upstairs also have connecting doors in edition to doors to the hallway. Any insight into the home’s style or age are so appreciated!
