“It is estimated that about 1400 Quakers, mostly English, emigrated to New Jersey and Pennsylvania before Penn's arrival, though the majority of these settled in West Jersey. ...Prominent among this group of early English Quakers was Robert Wade, who settled at Upland, bought 650 acres of land and built the famous 'Essex House,' at which was held in 1675 the first meeting of Quakers on Pennsylvania soil. Other early English settlers in the vicinity of Upland were John Test, Walter Wharton, Richard Noble, and Richard Bovington.”
