Volume 12 is a transcription of the vital records of the early and important towns of Fairfield and Farmington, and it contains the birth, marriage, and death records of approximately 37,500 individuals. Entries are in strict alphabetical order by town and give, typically, name, date of event, names of parents, names of children, names of both spouses, and items such as age, occupation, and residence. As in all volumes published to date, entries are keyed to the volume and page number of the original records.
