Researching Homes
The following are some great sources for researching your old Somerville home.
See also Researching your Historic Home at the Registry of Deeds

Word of Mouth
The first step should always be to talk to your neighbors. Ask them if they know anything about the history of your house or neighborhood. If possible, talk to previous owners. Any information you can glean from others will make your research easier.

Primary Sources: City and County Government
Primary sources are firsthand records of events—such as government documents, business records, or manuscripts

Deeds describe a property, state its worth, and name the owner. The current deed should also include the deed book number and page number of the previous owner's deed-ideally you should be able to trace a chain of ownership back to the construction of the house. Deeds for Somerville properties are held at the Middlesex Registry of Deeds, 208 Cambridge Street in East Cambridge. 617 679-6310. M-F 8-6, Sat. 8-12.
Wills and Probate Records
Probate records are the records created for the public supervision of an individual's property upon his death. Probate records usually include wills and an inventory of the deceased's estate. Somerville probate records are filed at the Middlesex Registry of Probate (across the street from the Registry of Deeds) 617 679-6310. M-F 8-4.
Building Permits
Somerville Building Permits are located at the Inspectional Services Department in the Department of Public Works Building at 1 Franey Road. Inspectional Services has original building permits from 1895 to the present, as well as “jacket files” (records of home repairs and alterations) from 1940 to the present. Office Hours: M-F 8 a.m.-4 p.m. Best hours to visit—10 a.m.-3 p.m

In the Library
The Somerville Public Library has numerous resources—maps, city directories, architectural guides—that can teach you about the history of your neighborhood, find out who lived in your house before you, and possibly identify when it was built.
