To qualify for membership in the National Society of Daughters of Founders and Patriots of America (NSDFP), one must possess a Founder ancestor who arrived in one of the colonies between May 13, 1607, and May 13, 1686, and a Patriot ancestor who rendered military service, civil service, or aid in establishing American Independence in the period 1775 to 1784. In 1975 the National Society published an index to its lineage records. From its founding until 1975, NSDFP published thirty-four volumes of lineage records (available at many libraries), encompassing the proven lineages of its membership. It should be pointed out that the volumes refer to a combined 9,275 Founders and Patriots. In 1975, recognizing the need for preserving those hallowed names in a single volume and for making it easier for persons to ascertain if they were qualified for membership in this unique and beloved patriotic society, NSDFP published this Index to the lineage records.
