Middlesex County, Massachusetts Genealogy

Guide to Middlesex County, Massachusetts ancestry, genealogy and family history, birth records, marriage records, death records, census records, family history, and military records.

Description
Middlesex County was one of the four original counties when Massachusetts Bay Colony created counties in 1643. When established, it had no defined western or northern border. These borders were more clearly defined when Worcester County was created in 1731 on the west and the Province of New Hampshire in 1680 to the north, but this border remained in dispute until 1741. Early settlers in this county went north, west, and south to establish new settlements in the 1600s and 1700s. The oldest college in the United States was established in Cambridge in 1636 - Harvard College, now Harvard University. Lowell, on the Merrimack River, became one of the centers of the Industrial Revolution in the mid-1800s that drew many immigrants to work in the mills, especially Irish and French-Canadian. The county government was abolished on 1 July 1997, but its former jurisdiction is used for state offices as a district.

The county was named for Middlesex, England. It is located in the North-central area of the state.

Land and Property Records
Land transfers, commonly called deeds, are recorded on the county level in Massachusetts. Not all deeds were recorded as is common practice today. The earliest transactions were charters or grants from the English Crown. Once local government was established, the colony would grant land to settlers directly or to towns to dole out. Some towns first start out as proprietorship and records were recorded there. Once towns were established, deeds were recorded on the county level. Middlesex County is divided into two districts. The county was one district until the creation of the Northern District in 1855. The original records are held by the Registry but closed to the public. Middlesex North Registry of Deeds 360 Gorham Street Lowell MA 01852 Phone 978-322-9000 Email [mailto:lowelldeeds@comcast.net lowelldeeds@comcast.net] Website This district includes Billerica, Carlistle, Chelmsford, Dracut, Dunstable, Lowell, Tweksbury, Tyngsborough, Westford, and Wilmington.

Probate Records
Probate and Family Court is organized on a county level in Massachusetts since the creation of the counties. The main records genealogists seek are testate (wills), intestate (administrations), guardianships, and divorces (since 1922), though there are many more that are valuable to any researcher, too. See a further discussion of the topic in general on the Massachusetts page.

Middlesex County operates one office for the entire county holding all the records. Most probates are handled by one of the four satellite offices in the county.
