Here's a story of one of the first slave owners in America:
Anthony Johnson "..developed a successful farm. In 1651 he owned 250 acres, and the services of four white and one black indentured servants. In 1653, John Casor, a black indentured servant whose contract Johnson appeared to have bought in the early 1640s, approached Captain Goldsmith, claiming his indenture had expired seven years earlier and that he was being held illegally by Johnson. A neighbor, Robert Parker, intervened and persuaded Johnson to free Casor.
Parker offered Casor work, and he signed a term of indenture to the planter. Johnson sued Parker in the Northampton Court in 1654 for the return of Casor. The court initially found in favor of Parker, but Johnson appealed. In 1655, the court reversed its ruling. Finding that Anthony Johnson still "owned" John Casor, the court ordered that he be returned with the court dues paid by Robert Parker.
This was the first instance of a judicial determination in the Thirteen Colonies holding that a person who had committed no crime could be held in servitude for life.
Though Casor was the first person declared a slave in a civil case, there were both black and white indentured servants sentenced to lifetime servitude before him." (Source - Anthony Johnson - Wiki)
The kicker: Anthony Johnson was a black man.
