To "manumit" is to release, set at liberty, or free from servitude a person from slavery or bondage. Genealogists may find this term in early New England colonial probate records. For example, in the last will and testament of Abraham Booth of Pembroke, Massachusetts, dated 10 August 1742, he "manumited his negroman (slave) Duk". Some authorities define the word "emancipate" to be a synonym for manumit.
