The materials cover the entire state of Connecticut and even include information on some families whose ancestry is associated with other areas, largely Massachusetts, New York, Vermont, and the Midwest. What you can learn about each listed individual varies, depending on the original article. However, in this collection you will find birth, death, marriage, probate, land, and court records.
