Great Migration
From Salem Links and Lore
The Great Migration describes the early wave of European immigrants to New England in the years roughly between 1620-1640. In the largest wave, there were upwards of 20,000 English immigrating to New England between 1630 and 1640. As a rough estimate about fifteen percent of immigrants to New England arrived in the fourteen years from 1620-1633, with the remaining eighty-five percent coming over half as many years, from 1634 to 1640.
