Margaret Brent also received credit or headrights for the five men and four women servants she had brought with her, and additional headrights for indentured servants she later imported (some of whose indentures she sold to other colonists). The colony's Proprietor issued headrights to encourage the gentry and sea captains to transport workers for labor in the growing colony. However, records concerning her trading or exercise of the headrights are missing, whether because lost or nonexistent, given the colony's instability. Brent became an ally of the governor, Leonard Calvert. Together they became guardians of seven-year-old Mary Kittamaquund, the daughter of a Piscataway chief, whose deathly ill son had recovered under the ministrations of Jesuit Rev. Andrew White. The colonists promised to educate the young girl in English language and culture. In 1644, Giles Brent married Mary Kittamaquund. Upon her father's death, he asserted his rights to tribal lands, contrary to both tribal custom and Governor Calvert's own claims.
