Very early settlement of New Jersey

My Moore group has been chatting about our Cureton ancestors.  James and Rose Moore's son John married Jane Cureton.  It is quite clear that Jane's family came over on the ship the Swan in 1685.  They settled in the Welsh Tract almost immediately.  However, we are not as certain how our Moore ancestors came to these shores.  We find James and Rose Moore in what is now downtown Philly by 1684....just two years after Penn had the city laid out.  Had they moved to these shores before and had been living elsewhere?  Did they move just in time to buy land in the new Philadelphia?  Our group is not sure.  We also are not sure just where they were living before they climbed on board a boat that brought them to our shores.
