Andrews, The Colonial Period of American History (4 vols., New Haven, 1934-38), I, chap. 18; and Carl Bridenbaugh, Vexed and Troubled Englishmen (New York, 1967), chaps. 11, 12; Puritan movement to the Caribbean is the subject of A. P. Newton, The Colonising Activities of the English Puritans (New Haven, 1914), and Susanna Fischer, “The Providence Adventure” (thesis, Princeton, 1983); for emigration to Ireland see Philip S. Robinson, The Plantation of Ulster; British Settlement in an Irish Landscape, 1600-1670 (Dublin, 1984).
   On the history of the great migration, the Essex County Record Office in Chelmsford, Essex, contains in its reading room many unpublished dissertations, both British and American, touching various aspects of this subject. Of particular value is Norman C. P. Tyack, “Migration from East Anglia to New England before 1660” (thesis, Univ. of London, 1951); David Cressy, Coming Over: Migration and Communication between England and New England in the Seventeenth Century (Cambridge, 1987).
