ly Ormsby wrote this guidebook as an outgrowth of her decades of participation in lineage organizations. She begins with a description of what they have in common, what they aim to do, how to find the right society for yourself, and the various eligibility requirements. She then explains the membership application process, including assembling the genealogical evidence for membership. She also gives examples of the social, cultural, and patriotic activities undertaken by lineage societies. Appendix A describes the membership requirements and contact information for many lineage societies. There is also a bibliography of sources.
