Welcome to Genealogy Trails!

Hello and welcome to the Genealogy Trails website for Baltimore County.

Volunteers Dedicated to free genealogy
Our goal is to help you track your ancestors through time by transcribing genealogical and historical data and placing it online for the free use of all researchers.

This website is in need of a dedicated host!

This is a continuation of our original Illinois Genealogy Trails project and we are excited about this opportunity to expand into other states. We welcome your feedback and comments, and of course, your data contributions.

We're looking for folks who share our dedication to putting data online and are interested in helping this project grow.

If you think you might be interested in hosting a county website such as this one, please view the Volunteer Page for further informationand contact Kim.

Baltimore County map

The name of the county was derived from the barony of the Proprietor of the Maryland colony, Cæcilius Calvert, 2nd Baron Baltimore, in County Longford, Ireland. The County Seat is Towson.

It should be noted that Baltimore County does not include the City of Baltimore, which was split off as an independent city in 1851.

The origin of Baltimore County is not known, the earliest known record of the county politically is January 12, 1659, when a writ was issued to its sheriff. Previously, Baltimore County was more known as a geographical entity than a political one, with its territorial limits consisting of the present day Baltimore City, Cecil and Harford Counties, as well as parts of Carroll, Anne Arundel, Frederick, Howard and Kent Counties.

In 1674, a portion of Baltimore County, as well as a portion of Kent County, was split off to form Cecil County. In 1748, a portion of Baltimore County, as well as a portion of Prince George's County, was split off to form Frederick County. In 1773, Harford County was split off from Baltimore County. In 1837, a part of Baltimore County was combined with a part of Frederick County to form Carroll County. In 1851 the city of Baltimore was detached from Baltimore County.
