The following discusses Quaker immigration from Ireland, as described by Myers, 1902.

THE migration may be considered in three waves. The first wave, beginning in 1682 and continuing to 1710, was caused largely by the severe religious persecutions carried on against the Friends before the Act of Toleration of 1683 was passed. The wave was the heaviest in 1682 and 1683, thirty-two adult colonists com- ing over in these two years. After this, the wars of James and William coming on, there was little migration until 1708.
From 1710 the stream [of the] second wave continued to flow steadily, reaching the highest point of the whole migration in the great famine year of 1729, when sixty-four adults came over. After 1710, the economic causes of migration were probably more potent than the religious.
The third wave reached its highest point in 1736, when thirty-three adult settlers arrived. From 1741, the movement declined, and after 1750 very few Friends came over to settle.
