How old is my house?
Sounds like the exact kind of construction on a house we restored a few years ago. It was on a covered wagon route and was built about 1900, but I’m located “out west”.

I’d check with the local chapter of the Historic Preservation Office. (They’re a division of the Federal Department of the Interior.) They will have accurate info on type of construction in your area. 

If you decide to restore it to their standards, there are some “big” tax savings, like your property taxes are frozen at the current value for 15 years or so, etc. However, you have to use their recommendations for windows, siding, etc. (Things like roofing can be anything, because it’s considered something that needs to be replaced from time to time, but check with them.)
