The Maryland State Archives Online is constantly changing, which can be confusing for users but more often presents new opportunities for research without leaving home. Today I want to draw your attention to the Legacy of Slavery in Maryland database. Now expanded and easier to use, this database includes more than 300,000 names of people both black and white. It searches Census records from 1776-1880, and 26 additional categories of records, including runaway ads, chattel records (sales of slaves), manumissions, slave jails, accommodations docket (fees for housing runaways), and assessment records (assessments of slaves in estate inventories). Most of the records are from 1830-1880. The database provides basic information, sometimes a description of the person, the name of the owner, and a full citation to the Maryland State Archives (MSA) Record Series from which the information has been transcribed.
Runaway ads can be extremely important sources of information. Slaveholders provide the most complete information about a slave when in it is their interest to do so, so the ads often include personal characteristics and skills, as well as full name, appearance, height, and distinguishing marks. They also include speculation about where the runaway might be headed, and most often that is back to where they came from or where they have family members. Browsing the ads for runaways from Magruder plantations, I’ve learned that one man likes to dress well; that another is a good carpenter; that a woman is an excellent cook; that another woman talks too much; that another man had been free to hire himself out in Washington City, but had recently disappeared, probably headed for Baltimore and then to Pennsylvania and freedom.
Good luck in your search.
