That is correct, thanks for the info. Nevertheless, even NJ had technically abolished slavery decades earlier and was in the process of completely eliminating the institution. What they created was some sort of weird "indentured servant" clause, but in effect the people were still slaves. The last 13 slaves/"indentured servants" were freed in 1865.
The indentured servants, slaves for a limited time period happened in other Northern States as well.
http://slavenorth.com/paemancip.htm...Yet the passage of the 1780 act ending slavery in the state reversed this trend and started indentured labor on a sudden, sharp recovery. From fewer than 400 at the end of the Revolution, Philadelphia's indentured servant population reached 2,000 by the end of the century....
....The indenture system in Pennsylvania became more severe after 1780, because the terms of service were longer. Formerly it had been limited to about seven years, and it rarely exceeded four among immigrants. Indentures generally had not lasted past age 21, for males, and 18, for females. This allowed at least the pretense of the bondsman or woman learning a trade (housework, almost always, in the case of the women) in exchange for their labor and being sent out into the world with at least a decade of productive labor or family life ahead. This was no quibble in an age when debility at 40 was common and many laboring people did not live to see 30.
Yet in Pennsylvania after 1780, the bound labor contract began to take 28 as the age of freedom. The abolition act had made it so, setting this as the age of release of children of slaves, and it would have seemed unjustified not to also do so in other cases. Shortly after the act was passed, the overseers of the poorhouse in Philadelphia began binding out children of black paupers up to age 28....
Name a southern state that was in the process of abolishing slavery even on NJ's terms.
While there was limited abolitionist support in the South, I am not aware of any state government actions along those lines in states that formed the Confederacy.
