Here is some information from "The Harvey Book" by Oscar Jewell Harvey, and from some other sources:
There was a large emigration from Scotland to East New Jersey in 1685. At that time the Province already had within its borders a considerable number of Scotch settlers, who had immigrated thither during the preceding five or six years. Of this number was RICHARD PITTENGER, who was born in Scotland about 1650, and died in New Jersey in the Summer of 1715. Letters of administration upon his estate were granted to his son John Pittenger 16 Oct., 1715, "by His Excellency Brigadeer Hunter."
