Dual Membership in Multiple Lineage Societies

Holding membership in more than one lineage society simultaneously is a well-established practice among hereditary organization participants in the United States. This page covers how dual and multiple membership works across major societies, the scenarios that most commonly give rise to it, and the factors that guide decisions about pursuing membership in more than one organization. Understanding the structural differences between societies — their eligibility criteria, documentation standards, and governance models — is essential for navigating multiple memberships effectively.

Definition and scope

Dual membership, in the context of hereditary societies, refers to an individual holding active membership in 2 or more distinct lineage organizations at the same time. The term "multiple membership" is used when the count exceeds 2. Neither arrangement is unusual: the National Society Daughters of the American Revolution (NSDAR), the General Society of Mayflower Descendants, the Sons of the American Revolution (SAR), and the Society of Colonial Wars all recognize that their members may simultaneously hold membership in other qualifying organizations.

Each lineage society functions as an independent body with its own bylaws, membership criteria, and dues structures. There is no central regulatory authority overseeing cross-society membership in the United States; each society governs its own admissions independently. The scope of dual membership therefore extends across three broad classification types:

1. Same-era, different society — membership in 2 organizations that draw eligibility from the same historical period (e.g., both the NSDAR and the SAR for Revolutionary War ancestry, when gender eligibility permits)
2. Cross-era membership — membership in organizations anchored to different historical periods, such as combining a colonial-era society with a Civil War–era society
3. Cross-type membership — membership spanning structurally different society types, such as holding membership in both a military lineage society and an ethnic lineage society

The key dimensions and scopes of lineage society membership — including era, geographic focus, and ancestor type — directly shape which combinations are logistically and genealogically feasible.

How it works

Each society conducts its own independent application and verification process. A person pursuing membership in 3 organizations must complete 3 separate applications, submit 3 sets of supporting genealogical documentation, and satisfy each society's specific proof standards. No society accepts another society's approval as a substitute for its own review.

The process for dual membership follows these discrete phases:

1. Lineage audit — The applicant identifies all qualifying ancestral lines. A single family tree may contain ancestors qualifying for 4 or more distinct societies, particularly if the tree includes colonial settlers, Revolutionary War participants, Civil War veterans, and immigrant founders of ethnic communities.
2. Documentation assembly — Vital records, military service files held by the National Archives and Records Administration (NARA), church records, and census schedules are compiled for each qualifying line. Different societies impose different evidentiary thresholds; the Mayflower Society, for instance, requires proof of an unbroken lineage to one of the approximately 102 passengers who survived the first winter at Plymouth.
3. Sequential or parallel application — Applications can be submitted simultaneously or in sequence. Submitting in sequence allows approved lineage documentation from one society to serve as a reference point (though not a substitute) when preparing a second application along the same ancestral line.
4. Independent fee payment — Each society charges its own application fee and annual dues. The lineage society annual dues and fees structure varies considerably; dues at a local chapter level may differ from national dues within the same organization.
5. Chapter affiliation — Most societies require affiliation with a local or state chapter in addition to national membership, which means dual membership may also involve dual chapter obligations.

Common scenarios

The 4 most frequently encountered patterns of dual membership in the United States are:

Revolutionary War combinations. An individual with documented Revolutionary War ancestry who meets gender eligibility may join both the NSDAR and organizations such as the Order of the Founders and Patriots of America if their lineage extends to the colonial period as well. Male applicants may pursue both the SAR and the Society of Colonial Wars.

Mayflower plus Revolutionary. Descendants of Mayflower passengers frequently hold membership in both the General Society of Mayflower Descendants and a Revolutionary War society, since the 150-year gap between 1620 and the 1770s means many Mayflower lines extend forward to include Revolutionary participants.

Military plus patriotic hereditary. A lineage that includes a Civil War ancestor may qualify for the Military Order of the Loyal Legion of the United States (for officers' descendants) while the same family tree supports membership in a broader patriotic hereditary society. The distinction between patriotic hereditary societies and lineage societies is relevant here, as admission standards differ between the two structural types.

Ethnic and era-based combinations. Applicants with ancestry from specific national or cultural groups may hold membership in an ethnic lineage society alongside an era-anchored organization. These 2 memberships draw on different qualifying criteria — cultural descent in one case, a specific historical service event in the other — and seldom involve documentation overlap.

Decision boundaries

Several structural factors determine whether pursuing multiple memberships is practical for a given individual.

Genealogical completeness. Multiple membership is only viable if the applicant can document each qualifying line to the standard required by each respective society. A partially documented line may support one application but not meet the stricter evidentiary requirements of a second organization. Resources such as proving lineage for society membership and guidance on documentation required for lineage society applications clarify what each tier of proof demands.

Financial commitment. Holding 3 active memberships simultaneously may require payment of 3 sets of national dues plus 3 sets of chapter dues annually. Applicants should review the fee schedules of each target society before initiating parallel applications.

Time and participation obligations. Many societies expect members to participate in chapter activities, volunteer for service programs, or fulfill governance roles. The lineage society community service and philanthropy obligations of 3 organizations can compound meaningfully for active members.

Redundancy assessment. Two societies with identical or nearly identical eligibility criteria — both requiring documented descent from a Revolutionary War patriot, for example — deliver overlapping social and genealogical validation. Applicants may find that a single membership in the more prominent organization satisfies their objectives without the administrative burden of a second parallel application.

Single-ancestor versus multi-ancestor structures. As explained in the discussion of single-ancestor vs. multi-ancestor lineage societies, societies organized around one specific founding individual (such as a Mayflower passenger) impose a narrower qualifying gateway than those accepting any ancestor who served in a particular war or era. Single-ancestor societies are generally more selective and may require additional genealogical research investment per application.
