Question: When did the Mayflower set sail from the country where Albert Cox's birth place's located?

full_context: Document 1: 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 2: 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 4: 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 15: 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.
