Some good results were obtained by the missionaries of the Society of North Carolina, but difficulties were also encountered there.  The chief trouble seems to have been that missionaries of that colony were “frustrated by the slave owners who would by no means permit” their Negroes to be baptized, “having a false notion that a christened slave is by law free."[11] “By much importunity,” says an investigator, Mr. Ransford of Chowan (in 1712) prevailed on Mr. Martin to let him baptize three of his Negroes, two women and a boy.  “All the arguments I could make use of,” said he, “would scarce effect it till Bishop Fleetwood’s sermon (in 1711) ... turned ye scale."[12] Mr. Rumford succeeded, however, in baptizing upwards of forty Negroes in one year.  In the course of time, when the workers overcame the prejudice of the masters, a missionary would sometimes baptize fifteen to twenty-four in a month, forty to fifty in six months, and sixty to seventy in a year.[13] Reverend Mr. Newman, a minister in North Carolina, reported in 1723 that he had baptized two Negroes who could say the Creed, the Lord’s Prayer, the Ten Commandments, and gave good sureties for their further information.[14] According to the report of Rev. C. Hall, the number of conversions there among Negroes for eight years was 355, including 112 adults, and “at Edenton the blacks generally were induced to attend service at all these stations, where they behaved with great decorum."[15]

In the Middle and Southern Colonies these missionaries had the cooperation of Dr. Thomas Bray.  In 1696 he was sent to Maryland by the Bishop of London to do what he could toward the conversion of adult Negroes and the education of their children.[16] Bray’s most influential supporter was M. D’Alone, the private secretary of King William.  D’Alone gave for the maintenance of the cause a fund, the proceeds of which were first used to employ catechists, and later to support the Thomas Bray Mission after the catechists had failed to give satisfaction.  At the death of this missionary the task was taken up by certain of his followers known as the “Associates of Dr. Bray."[17] They extended their work beyond the bounds of Maryland.  These benefactors maintained two schools for the benefit of Negroes in Philadelphia.  About the close of the French and Indian War, Rev. Mr. Stewart, a missionary in North Carolina, found there a school for the education of Indians and Negroes conducted by “Dr. Bray’s Associates."[18]

Georgia too was not neglected.  The extension of the work of Dr. Bray’s associates into the colony made an opening there for taking up the instruction of Negroes.  The Society joined with these workers for supporting a schoolmaster for Negroes in 1751 and an improvement in the slaves was soon admitted by their owners.[19] In 1766 Rev. S. Frink, a missionary toiling in Augusta, found that he could neither convert the Indians nor the whites, who seemed to be as destitute of religion as the former, but succeeded in converting some Negroes.[20]
