St. James's parish was separated from St. Martin's in 1685, but before that epoch it had begun to have an existence of its own. Faithorne and Newcourt's map of London, 1658, shows us open ground from a double row of trees at Pall Mall to Piccadilly; Piccadilly is marked "from Knightsbridge unto Piccadilly Hall." Opposite the palace, at the foot of the present St. James's Street, are a few houses, including Berkshire (now Bridgewater) House, and there are a few more at the eastern extremity of Pall Mall. At the north-eastern corner of what we call the Haymarket is the "Gaming House," and at the corners adjacent one or two more buildings. This is St. James's in its earliest stage, before the tide of fashion had moved so far westward. Henry Jermyn, Earl of St Albans, in the reign of Charles II. obtained a building lease of forty-five acres in St. James's Fields and projected the square, which became the nucleus of the parish. _Piccadilly._--There is no authentic derivation for this curious name, though many fancy suggestions have been made. The most probable of these is that which connects it with the peccadilloes or ruffs worn by the gallants of Charles II.'s time. Pennant traced the name to piccadillas, turnovers or cakes which were sold at Piccadilla Hall, at the upper end of the Haymarket. In Thomas Blount's "Glossographia" we read: "Pickadil ... the round hem or the several divisions set together about the skirt of a garment or other thing; also a kinde of stiff collar made in fashion of a Bande. Hence perhaps that famous ordinary near St. James called Peckadilly took denomination because it was then the utmost or skirt house of the suburbs that way, others say it took its name from this, that one Higgins a tailor who built it got most of his estate by Pickadilles, which in the last age were much worn in England." There seems to be no other foundation than Mr. Blount's lively imagination for "Higgins a tailor."
