Definition
The lineage or line of ancestors from which a person descends; an account or register of ancestral relationships, including facts of birth, marriage, and death within a family line.
In legal usage, pedigree carries two related but distinct meanings:
1. Substantive meaning: The state of a family as regards the relationship of its members — their births, marriages, deaths, and the times when those events occurred. Pedigree in this sense is the subject matter of inquiry when property rights, inheritance, or family status depend on proving kinship or descent.
2. Evidentiary meaning: A recognized category of evidence law concerning how facts of family history may be proved. Because pedigree facts typically arise in remote times and cannot be established by living witnesses with direct knowledge, courts have long admitted hearsay evidence on questions of pedigree as an exception to the general rule excluding hearsay. Declarations made by deceased family members regarding births, marriages, deaths, and relationships are admissible under this exception, provided the declarant was related to the family and the declaration was made before the controversy arose.
Common Language
Modern common usage (Wiktionary): A chart, list, or record of ancestors showing breeding, especially distinguished breeding; a person's ancestral history or lineage; also the ancestry of a domesticated animal, especially a dog or horse.
Historical common usage (Webster's 1913): A line of ancestors; descent; lineage; genealogy; a register or record of a line of ancestors. Used freely in reference to both human families and animal breeding.
The legal meaning tracks the common meaning closely in its genealogical sense, but the law adds a dimension the common definitions do not capture: pedigree as a term of evidence, governing what proof is admissible and who may supply it. A researcher encountering "pedigree" in a legal source must determine whether the author is describing family history as a subject of inquiry or invoking the rules governing how that history may be proved. Common usage collapses this distinction entirely.
Core Elements
For the hearsay exception to apply to pedigree evidence, courts have generally required:
1. Relationship: The declarant must have been a member of, or intimately associated with, the family whose pedigree is in question.
2. Ante litem motam: The declaration must have been made before the controversy or litigation arose, so the declarant had no motive to fabricate.
3. Death of declarant: The declarant must be unavailable, typically by death, so that direct testimony cannot be obtained.
4. Subject matter: The declaration must concern facts of family history — birth, marriage, death, descent, or relationship — not merely general reputation.
5. Pedigree in issue: The relationship or family status must be genuinely in issue in the proceeding, not merely a collateral matter.
Why It Matters in Research
Pedigree questions arise most frequently in three research contexts: inheritance disputes (heirship proceedings, intestate succession), claims dependent on legitimacy or adoption, and actions involving the devolution of entailed or settled property under older real property law. Researchers working with pre-twentieth-century sources will encounter pedigree questions far more often and in more elaborated form than in modern materials, because the rise of systematic civil registration of births, marriages, and deaths gradually reduced reliance on hearsay declarations to establish family facts.
The evidentiary doctrine of pedigree is one of the older common law hearsay exceptions and was well-settled by the time the major historical dictionaries were compiled. Modern evidence codes — including the Federal Rules of Evidence — have codified versions of this exception, but the language and structure differ from the common law formulation. A researcher moving between historical cases and modern doctrine should not assume the requirements are identical.
The ante litem motam requirement is a frequent point of litigation and is sometimes stated imprecisely in older sources. Some authorities phrase it as requiring the declaration to predate the dispute; others require it to predate the specific controversy over property or status. This distinction can affect which declarations qualify, and researchers should read the original sources carefully rather than relying on dictionary paraphrases.
Pedigree evidence connects directly to the law of family reputation and to the broader hearsay exception for reputation in the community. These are related but not identical categories, and older treatises sometimes blur the line between reputation as to pedigree (statements within the family) and general community reputation (statements among neighbors). Modern codifications often separate them explicitly.
For animal pedigree — the registered ancestry of horses, dogs, or livestock — a distinct body of commercial and regulatory law governs, entirely separate from the evidentiary doctrine. Researchers encountering "pedigree" in agricultural, racing, or kennel club contexts are in a different legal universe from the evidence and family law materials.
Historical Dictionary Support
The historical dictionaries converge on the genealogical core of the definition without significant disagreement. Black's (both editions) defines pedigree as lineage, line of ancestors, and family relationship. Bouvier elaborates usefully, describing pedigree as "a succession of degrees from the origin" encompassing the state of a family as regards births, marriages, deaths, and relationships — and immediately pivoting to the evidentiary problem: because such facts are remote in time and living witnesses are unavailable, hearsay evidence has been admitted. Anderson's similarly emphasizes that all authorities agree pedigree may be proved by reputation, i.e., hearsay, and specifies that the term embraces not only descent and relationship but also the events of birth, marriage, and death.
Rapalje & Lawrence's entry is fragmentary in the source material provided, with the pedigree content apparently cut off mid-sentence, but the surviving text confirms the evidentiary framing: in proceedings concerning the devolution of a deceased person's property, questions as to the relationship of claimants are called "questions of pedigree."
What the historical dictionaries handle less fully is the ante litem motam requirement and the precise scope of who qualifies as a competent declarant. These details are better developed in treatises on evidence — Greenleaf on Evidence being the classic authority — than in the dictionary entries. Researchers relying solely on dictionary definitions of pedigree will have the framework but will need to consult evidence treatises for the operational rules.
Jurisdictional Note
The hearsay exception for pedigree declarations is recognized across common law jurisdictions but codified with some variation. Under the Federal Rules of Evidence, statements of personal or family history are addressed in Rules 803(11), 803(13), and 804(b)(4), with differing requirements depending on whether the declarant is unavailable. Civil law jurisdictions handle proof of family status through civil registration systems and do not rely on the common law pedigree exception in the same way.
