If you want to research your property deeds you can do it all online:
http://www.nhdeeds.com/belknap/BeDisclaimer.html
1. Click on "Accept Registry Disclaimer"
2. After the window for the database loads, you can enter your search criteria starting for 1955 - Present just by entering the name of the Grantor or Grantee or Plans or a combo of the Grantor/Grantee.
3. For pre-1955, under the heading of "Select Index", click on the drop down menu and select "Old Index Books" and you can go back to about 1841, although many deeds will contain historic information about the property, such as the year a stonewall was built or repairs were made to the house.
The old deeds are a trip to read - and they are handwritten.
Enjoy!
