This publication is a key to the lineage records of members of the National Society Colonial Dames. The base work is a complete list of the 8,000 seventeenth-century ancestors from whom descent has been positively proved by members of this prestigious hereditary society. As a rule, each entry gives the name of the colonial ancestor, his dates of birth and death, the name of his wife, his colony of residence, and his occupation or service. To the original list of 8,000 seventeenth-century ancestors from whom descent has been positively proved, Supplement 1 adds the names of 2,500 additional ancestors from whom descent was proved by members of the Society between 1975 and 1979. Supplement 2 contains the names of an additional 2,500 ancestors from whom descent was proved by members of the Society between 1979 and 1988.
