Finding history of house
"Contact your local Preservation Society or Historical Society for info."
Since there is a plaque, your house is probably registered, and I believe you are REQUIRED to submit ANY remodelling changes for review/approval by your local Preservation Society or Historical Society. This can be a problem if you want to update certain aspects of the house including landscaping!
I had a 'second thought'. If there are other restored homes in the area that look 'authentic', your question would be 'nice' way to introduce yourself to them.
Yes, good luck and enjoy your home.
