According to its website, “The permanently valuable records of State government are available in our Research Room. They include bills introduced in the Legislature, Governor’s Executive Orders, election returns, deeds to and from the State of Maine, maps from the Land Office, vital statistics, federal census records from Maine up to 1920, county court records dating back to the 1600’s, military records through World War I, Attorney General and State Supreme Court opinions, to name only a few.”
The Archives has information which can be of use to those pursuing family history. These records, many of them on microfilm (including U.S. Census records), can be viewed at the Archives in Augusta.
While the staff does not conduct genealogical research, it does maintain a list of professional genealogists who do so for a fee.
