Question: when did the mayflower set sail from the country encompassing Chester -le- street?

full_context: Document 1: County Street Historic District: The County Street Historic District is a historic district roughly bounded by Acushnet, Page, Middle, and Bedford streets (both sides) in New Bedford, Massachusetts, USA. The district was a fashionable residential area populated by the city's elite from 1780 to about 1890, and includes the city's major civic buildings, including City Hall, the public library, post office, and registry of deeds. County Street, its major roadway, was first laid out early in the 18th century.
Document 2: Mayflower: In early September, western gales began to make the North Atlantic a dangerous place for sailing. The Mayflower's provisions were already quite low when departing Southampton, and they became lower still by delays of more than a month. The passengers had been on board the ship for this entire time, and they were quite worn out and in no condition for a very taxing, lengthy Atlantic journey cooped up in cramped spaces in a small ship. But the Mayflower sailed from Plymouth on September 6, 1620 with what Bradford called ``a prosperous wind ''.
Document 3: Conímbriga: Conímbriga is one of the largest Roman settlements excavated in Portugal, and was classified as a National Monument in 1910. Located in the civil parish of Condeixa-a-Velha e Condeixa-a-Nova, in the municipality of Condeixa-a-Nova, it is situated from the municipal seat and from Coimbra (the Roman town of "Aeminium").
Document 4: Lancashire: The county was established in 1182, later than many other counties. During Roman times the area was part of the Brigantes tribal area in the military zone of Roman Britain. The towns of Manchester, Lancaster, Ribchester, Burrow, Elslack and Castleshaw grew around Roman forts. In the centuries after the Roman withdrawal in 410AD the northern parts of the county probably formed part of the Brythonic kingdom of Rheged, a successor entity to the Brigantes tribe. During the mid-8th century, the area was incorporated into the Anglo-Saxon Kingdom of Northumbria, which became a part of England in the 10th century.
Document 5: Coney's Castle: Coney's Castle is an Iron Age hill fort in Dorset, England. The name "Coney" is from the Old English for "rabbit" (Latin "cuniculus"), suggesting medieval use as a domestic warren, as at nearby Pilsdon Pen.
Document 6: Castra of Cristești: Although not unanimously accepted, the existence of the castra of Cristești in the Roman province of Dacia is substantiated by bricks and tiles bearing the name of a Roman military unit, the "Ala I Gallorum et Bosporanorum". The lack of any other traces of the Roman fort may easily be due to its destruction by the Mureș River. At Cristeşti, a Roman settlement from the 2nd and 3rd centuries AD was unearthed which was an important center of potters.
Document 7: Mayflower: The Mayflower was an English ship that famously transported the first English Puritans, known today as the Pilgrims, from Plymouth, England to the New World in 1620. There were 102 passengers, and the crew is estimated to have been about 30, but the exact number is unknown. This voyage has become an iconic story in some of the earliest annals of American history, with its story of death and of survival in the harsh New England winter environment. The culmination of the voyage in the signing of the Mayflower Compact was an event which established a rudimentary form of democracy, with each member contributing to the welfare of the community. There was a second ship named Mayflower that made the London to Plymouth, Massachusetts voyage several times.
Document 8: Vasco da Gama: Vasco da Gama left Calicut on 29 August 1498. Eager to set sail for home, he ignored the local knowledge of monsoon wind patterns that were still blowing onshore. The fleet initially inched north along the Indian coast, and then anchored in at Anjediva island for a spell. They finally struck out for their Indian Ocean crossing on 3 October 1498. But with the winter monsoon yet to set in, it was a harrowing journey. On the outgoing journey, sailing with the summer monsoon wind, da Gama's fleet crossed the Indian Ocean in only 23 days; now, on the return trip, sailing against the wind, it took 132 days.
Document 9: Southampton: The port was the point of departure for the Pilgrim Fathers aboard Mayflower in 1620. In 1912, the RMS Titanic sailed from Southampton. Four in five of the crew on board the vessel were Sotonians, with about a third of those who perished in the tragedy hailing from the city. Southampton was subsequently the home port for the transatlantic passenger services operated by Cunard with their Blue Riband liner RMS Queen Mary and her running mate RMS Queen Elizabeth. In 1938, Southampton docks also became home to the flying boats of Imperial Airways. Southampton Container Terminals first opened in 1968 and has continued to expand.
Document 10: Mayflower Steps: The Mayflower Steps are close to the site in the Barbican area of Plymouth, south - west England, from which the Pilgrim Fathers are believed to have finally left England aboard the Mayflower, before crossing the Atlantic Ocean to settle in North America on 6 September 1620. The traditional site of their disembarkation in North America is Plymouth Rock.
Document 11: Mayflower: Captain Jones became master of the Mayflower 11 years prior to the Pilgrims' voyage, sailing the ship cross-Channel taking English woolens to France and bringing French wine to London. In addition, he had also transported hats, hemp, Spanish salt, hops, and vinegar to Norway, and may have taken the Mayflower whaling in the North Atlantic in the Greenland area. She had traveled to Mediterranean ports, being then owned by Christopher Nichols, Robert Child, Thomas Short, and Christopher Jones, the ship's master. In 1620, Jones and Robert Child still owned their quarter shares in the ship, and it was from them that Thomas Weston chartered her in the summer of 1620 to undertake the Pilgrim voyage. Weston had a significant role in the Mayflower voyage, due to his membership in the Company of Merchant Adventurers, and he eventually traveled to the Plymouth Colony himself.
Document 12: Strasbourg: The centre of Argentoratum proper was situated on the Grande Île (Cardo: current Rue du Dôme, Decumanus: current Rue des Hallebardes). The outline of the Roman "castrum" is visible in the street pattern in the Grande Ile. Many Roman artifacts have also been found along the current Route des Romains, the road that led to Argentoratum, in the suburb of Kœnigshoffen. This was where the largest burial places were situated, as well as the densest concentration of civilian dwelling places and commerces next to the camp. Among the most outstanding finds in Kœnigshoffen were (found in 1911–12) the fragments of a grand Mithraeum that had been shattered by early Christians in the fourth century. From the fourth century, Strasbourg was the seat of the Bishopric of Strasbourg (made an Archbishopric in 1988). Archaeological excavations below the current Église Saint-Étienne in 1948 and 1956 unearthed the apse of a church dating back to the late fourth or early fifth century, considered to be the oldest church in Alsace. It is supposed that this was the first seat of the Roman Catholic Diocese of Strasbourg.
Document 13: Mayflower: On November 9, 1620, they sighted present - day Cape Cod. They spent several days trying to sail south to their planned destination of the Colony of Virginia, where they had obtained permission to settle from the Company of Merchant Adventurers. However, strong winter seas forced them to return to the harbor at Cape Cod hook, well north of the intended area, where they anchored on November 11. The settlers wrote and signed the Mayflower Compact after the ship dropped anchor at Cape Cod, in what is now Provincetown Harbor, in order to establish legal order and to quell increasing strife within the ranks.
Document 14: Chester-le-Street: Chester-le-Street () is a town in County Durham, England. Its history goes back to the building of a Roman fort called Concangis. This Roman fort is the "Chester" (from the Latin castra) of the town's name; the "Street" refers to the paved Roman road that ran north–south through the town, and which is now called Front Street.
