Manumise

[…] it were a charytable dede to euery noble man […] to manumise them that be bonde and to make them free of body and blode

1612, John Davies, The Muses Sacrifice, London: George Norton, “A sicke Mindes Potion for all in Tribulation in Body,” p. 134, from death, made free; / And, manumiz’d from this Worlds mortall woes

Our Dear departed Brother lies in State; / His Heels ſtretch'd out, and pointing to the Gate: / And Slaves, novv manumis'd, on their dead Maſter vvait.

Neither is it uncommon for the men slaves to purchase and manumize their wives, and vice versa, the wives their husbands.
