One of the Separatist congregations was led by William Brewster and the Rev. Richard Clifton in the village of Scrooby in Nottinghamshire. The Scrooby group emigrated to Amsterdam in 1608 to escape harassment and religious persecution. The next year they moved to Leiden, where, enjoying full religious freedom, they remained for almost 12 years.

In 1617, discouraged by economic difficulties, the pervasive Dutch influence on their children, and their inability to secure civil autonomy, the congregation voted to emigrate to America.

Fewer than half of the group's members elected to leave Leiden. A small ship, the Speedwell, carried them to Southampton, England, where they were to join another group of Separatists and pick up a second ship. After some delays and disputes, the voyagers regrouped at Plymouth aboard the 180-ton Mayflower.

It began its historic voyage on Sept. 16, 1620, with about 102 passengers--fewer than half of them from Leiden. After a 65-day journey, the Pilgrims sighted Cape Cod on November 19.
