This is the fourth volume compiled by Mr. Boyle containing 18th-century Maryland runaway servant ads posted in local newspapers. It follows runaways during the period of the American Revolution, 1775-1781. The roughly 1,000 ads found here name between 3,000 and 4,000 persons--indentured servants, convict laborers, and African-American slaves--reflecting the fact that the transportation of servants and convicts into Maryland reached its height in the middle of the 18th century. Eighty percent of the runaways were males. In addition to an individual's age and whereabouts, the ads tell a great deal more about the character and physical appearance of runaways than we are accustomed to learning from most source records. These ads were compiled mainly from a half-dozen Maryland and Pennsylvania newspapers as well as from states as far north as Massachusetts.
