This is the ultimate authority on the ancestry and relationships of approximately 50,000 residents of Fairfield County, Connecticut. It is a vast compendium of family history, meticulously developed from original sources, and in every way an accurate reflection of the investigative genius of its celebrated author. Each family history commences with the original 17th-century settler and is brought down, in most cases, to the early decades of the 19th century. The accumulated data is further enhanced by abstracts of land and probate records, the effect of which is to add still more weight to the already overwhelming evidence. Throughout, families are arranged in alphabetical order. Children are carried forward as heads of families in leap-frog fashion, and everyone mentioned whose name does not occur in normal sequence under the appropriate family history is identified in the index. Wherever possible, women are indexed under their maiden names.
