How to Research Your Family History in Massachusetts

Massachusetts is the deepest-documented state in America. Towns have recorded births, marriages, and deaths since the 1620s and 1630s; the Commonwealth built the nation’s first comprehensive statewide registration system in 1841; the pre-1850 town records were published, town by town, in the famous “tan books”; and Boston hosts the oldest genealogical society in the world, whose library and databases cover New England wall to wall. The craft in Massachusetts is not finding records – it is knowing which of four layers (town, state registration, county registries, and the great collections) answers each question fastest.

Start With Vital Records

Two eras, both excellent:

Divorces are county-level court records (historically Supreme Judicial Court, later Probate and Family Court).

  • 1841 onward – statewide registration, the first true system in the country. The 1841–1925 returns are indexed and digitized (through the Massachusetts Archives and the major platforms), and later records come from the Registry of Vital Records and Statistics or town clerks. Massachusetts is unusually open: most vital records are public, with only narrow restricted categories – a researcher’s climate few states match.
  • Before 1841 – town records, kept by town clerks from settlement. For roughly 200+ towns, everything to 1850 was published a century ago in the Vital Records to 1850 series (“tan books”), alphabetized by surname; digitized copies are freely accessible. Start there, then verify in the town register, and remember church records (Congregational baptisms especially) fill what towns missed.

County Registries: Deeds And Probate – With District Traps

Land and estates are county business:

Counties in Massachusetts never held vital records – keep the layers straight.

  • Registry of Deeds – deed books from the 1600s (Suffolk’s and the other original counties’ first volumes are among America’s oldest), nearly all searchable free online through the state’s registry portal. The trap: several counties are split into multiple registry districts – Middlesex (North and South), Essex (North and South), Worcester, Bristol, and Berkshire among them – each district keeping its own books. A “missing” deed is often in the county’s other district.
  • Probate and Family Court – one per county, holding wills, administrations, inventories, and guardianships; the older county probate files (17th–19th century) have been gathered under the Judicial Archives at the Massachusetts Archives and are heavily digitized and indexed. Colonial-era Suffolk and Essex court files, published and archived, document early families in extraordinary depth.

The State Archives And The Judicial Archives

The Massachusetts Archives at Columbia Point (Boston) holds the colonial and state government record: the “Massachusetts Archives Collection” of colonial papers, legislative files, military rolls – including the seventeen-volume Massachusetts Soldiers and Sailors of the Revolutionary War, the standard service reference (covering Maine men too, since Maine was Massachusetts until 1820) – the 1855 and 1865 state censuses (both survive and are indexed), and the Judicial Archives’ court and probate transfers.

Nehgs: The Great Library

The New England Historic Genealogical Society (founded 1845, Boston) – operating online as American Ancestors – is the field’s oldest institution and Massachusetts research’s second home: the tan books, the flagship Great Migration Study Project profiling the 1620–1640 immigrants (if your line reaches early Massachusetts, someone has likely already documented it to a scholarly standard – verify rather than reinvent), manuscript genealogies, and databases including the digitized Catholic parish registers of the Archdiocese of Boston, a decisive source for the Irish and Italian generations.

Immigrant Massachusetts

Boston was a great immigration port: passenger lists (indexed online), naturalizations (state courts before 1906, then federal – the National Archives at Boston holds the federal files and dexterous indexes), and the ethnic parish and society registers of Irish, Italian, French-Canadian, Portuguese (New Bedford and Fall River, with Azorean parish registers digitized on FamilySearch), Jewish, and other communities. Mill-city directories track families almost annually.

Maritime And Special Paths

Whaling and seafaring families (Nantucket, New Bedford, Salem, Gloucester): crew lists at the National Archives, the New Bedford Whaling Museum’s crew databases, and Quaker meeting records for the Nantucket community. African American Massachusetts: town and church records include Black residents from the 1600s; add manumission-era court cases (slavery ended in Massachusetts through 1780s litigation), Prince Hall records, Boston directories, and the abolition-era press. Native ancestry: Wampanoag, Nipmuc, and other communities appear in colonial records, guardianship and “Indian account” files at the Archives, and tribal records – enrollment belongs to the nations.

Online And Free

The tan books circulate free. The registries’ deed portal is free. FamilySearch holds filmed town, probate, and church records and the 1841–1915 vital collections. American Ancestors (subscription; free tiers and library access widely available) carries the deepest Massachusetts-specific databases. The state censuses, directories, and newspapers sit on the major platforms, free through Massachusetts public libraries.

Research Checklist

  1. Sort every question by layer: town (vital), state (1841+ registration), county registries (deeds, probate), collections (NEHGS, Archives).
  2. Pre-1850 line: start in the tan books, verify in town and church registers.
  3. Deeds: identify the correct registry district – Middlesex, Essex, Worcester, Bristol, Berkshire all split.
  4. Probate: search the digitized county files through the Judicial Archives indexes.
  5. Great Migration ancestor? Check the published scholarship before re-deriving the line.
  6. Immigrant lines: pair port and naturalization records with the digitized Catholic registers.
