Are you defining the Pinelands as in the modern boundaries of the
Pinelands National Reserve?
I think most of the continuously settled places within that boundary sprung up in the 18th century. There wasn't really much reason for people to stay inside the Pinelands. Even the Lenape didn't really do much in the Pinelands except go through them on their way to the ocean.
The first iron furnace in New Jersey was built in 1674 in Tinton Falls, which is outside the Pinelands, so that'd be your earliest year for furnaces showing up. Batsto was founded in 1766. Atsion was completed in 1768. The Cedar Bridge Tavern was built in 1740. There were settlers at Tuckerton as early as 1698. In 1700 Jacob Ong bought 100 acres of land in Northampton Township, although Ong's Hat doesn't show up on the maps until Thomas Gordon's 1834 Gazetteer.
If you want to step outside the modern boundary of the Reserve, the area around Medford started seeing European Settlers show up in 1670. There's a cabin in Mauricetown that shows up in the 1690s.
Old maps aren't much help.
This map from 1685 doesn't show much in the way of settlements in the Pines.
A map from 1667 shows a comically empty New Jersey, with just some forts along the Delaware, which most likely were built by the Swedes. Interestingly the "Kleyne Eyer Haven", "Groote Eyer Haven", and "Barnegat" show up along the Atlantic coast.
