Connecticut Emigration and Immigration
Colonial settlers of Connecticut generally came from Great Britain and neighboring New England states. Descendants of these early settlers later scattered throughout northern New England, upstate New York, Pennsylvania, Ohio, and Texas.
Many Irish and German immigrants began coming in the late 1840s. French-Canadian immigration began after the Civil War and continued through the rest of the nineteenth century. Late in the century most immigrants came from the southern and eastern countries of Europe, including Italy, Hungary, Poland, and Russia.
The major port of entry to New England is Boston. The Family History Library and the National Archives have passenger lists for Boston for 1820 to March 1874 and 1883 to 1935 (listed in the Family History Library Catalog under MASSACHUSETTS, SUFFOLK, BOSTON - EMIGRATION AND IMMIGRATION). The following indexes are also available:
