Definition
Propinquity means nearness of blood relationship; kinship. In legal usage, the term refers to the degree of relatedness between persons connected by family ties, and is invoked primarily in the context of inheritance, succession, and the determination of who stands closest in line to take property from a decedent. The closer the propinquity, the stronger the presumptive claim.
The term appears most often in older authorities dealing with intestate succession, where the identity of heirs depended on calculating degrees of consanguinity. A person of nearer propinquity would exclude one of more remote propinquity from taking as an heir.

Common Language
Modern common usage (Wiktionary): Nearness or proximity; affiliation or similarity.
Historical common usage (Webster's 1913): Nearness in place; nearness in time; nearness of blood, kindred, or affinity.
The common meaning of propinquity includes physical proximity and temporal nearness — two senses entirely absent from its legal usage. In law, propinquity is restricted to blood relationship and degree of kinship. A researcher encountering the word in a general historical text should not assume the legal, genealogical sense; context determines which meaning governs.

Why It Matters in Research
Propinquity is a period term. It surfaces with regularity in pre-twentieth-century sources — particularly English and Scots law materials, treatises on descent and distribution, and ecclesiastical records dealing with inheritance — and falls away in modern American legal writing, where "degree of kinship," "consanguinity," and "next of kin" have largely displaced it.
Researchers working in the Law Mind corpus should be alert to several navigational points:
First, propinquity and consanguinity are not identical. Propinquity tends to describe the relational fact of nearness; consanguinity describes the legal or biological tie itself. The distinction matters in historical sources, where writers sometimes use the two interchangeably and sometimes distinguish them with care.
Second, the term has particular prominence in Scots law materials, where it carried technical weight in succession disputes. Burrill's citation to Bell's Dictionary signals this jurisdictional concentration. Researchers focused on English common law sources may find the term less frequently than those working in Scots or civil law traditions.
Third, because propinquity was used in degree-of-relationship calculations, it often appears alongside the canonical tables of consanguinity found in treatises on intestate succession and in canon law materials governing prohibited degrees of marriage. A researcher following propinquity into the corpus will frequently find themselves pulled toward both inheritance law and marriage law simultaneously — two bodies of doctrine that shared much of the same underlying kinship vocabulary.
Fourth, the term does not appear in modern American statutory codes under this name. Researchers searching digital corpora for this term will be working almost entirely in historical materials; the absence of hits in contemporary sources is expected, not a gap.

Historical Dictionary Support
The historical dictionaries are thin on propinquity, and they agree on the core meaning: kinship, parentage, the relational closeness among family members. Black's in both editions offers only a stub — "kindred; parentage" — with a cross-reference to the related Latin term PROPIOR SOBRINO (the nearer cousin), which itself reflects the graduated, degree-based thinking that underlies propinquity's legal function. Neither edition elaborates on how the concept operates in practice or distinguishes it from adjacent terms.
Burrill adds the most useful gloss, noting the Scots law context explicitly and sourcing the definition to Bell's Dictionary of the Law of Scotland. Burrill's entry also preserves the Latin root (propinquus, meaning near or close), which helps explain why the word carries its particular shade of relational nearness rather than the broader affinity sense that sometimes appears in ecclesiastical sources.
What the historical dictionaries collectively miss: they do not address how propinquity functioned as an operative concept in degree-of-kinship calculations, how it related to the civilian and canon law tables of consanguinity, or how its application might differ between jurisdictions that followed different counting methods (the civil law method versus the canon law method for computing degrees of relationship). Researchers relying solely on these dictionary entries will have the definition but not the doctrine.

Jurisdictional Note
Propinquity as a technical term carries more weight in Scots law and in jurisdictions historically influenced by civilian tradition than in standard English common law or American practice. In American legal materials, the concept survives under different vocabulary; the term itself is largely archaic in domestic sources after the nineteenth century.
