Definition
In the law of descent, the first purchaser is the ancestor who originally brought an estate into a family by any means other than inheritance. Once the estate passes by descent through subsequent generations, the person who first acquired it by non-hereditary means — whether by purchase, gift, grant, or any other conveyance — is identified as the first purchaser. The status matters because rules of descent historically traced back to this originating acquisition to determine how property would pass when the line of inheritance was disputed or broken.
The term operates as a technical marker in descent law, not a description of a commercial transaction. "Purchase" in this context carries its broadest common-law meaning: any acquisition of an estate by the act of the party, as opposed to the operation of law through inheritance.

Common Language
Modern common usage (Wiktionary): "First purchaser" in ordinary English means the first person to buy something — the initial buyer in a commercial transaction.
Historical common usage (Webster's 1913): Webster's treats "purchaser" as one who acquires property by buying it, i.e., by paying a price.
The gap here is significant. In descent law, "first purchaser" has nothing to do with a commercial sale. The ancestor who received an estate as a gift, or who received it by royal grant, is equally the "first purchaser" for purposes of this doctrine. Researchers encountering the term in historical property and probate materials must resist the instinct to read it as denoting a sale transaction.

Common Confusion
FIRST PURCHASER vs. PURCHASER FOR VALUE WITHOUT NOTICE: These are entirely distinct concepts. A purchaser for value without notice (a bona fide purchaser) is a doctrine in equity and conveyancing law protecting a buyer who acquires property without knowledge of prior equitable claims. The first purchaser in descent law is a historical categorization of an ancestor's mode of acquisition. Neither concept implies the other.
FIRST PURCHASER vs. ORIGINAL GRANTEE: Closely related but not always identical. An original grantee is the first recipient of a specific conveyance in the chain of title. The first purchaser in descent law is the ancestor at the root of a family's hereditary holding — which may or may not align with the original grantee in a chain of title depending on intervening transfers within the family before descent began.

Why It Matters in Research
This term appears almost exclusively in English common law materials governing the canons of descent — the rules that determined how real property passed to heirs when the owner died intestate. Its practical importance declined sharply after statutory reforms altered and eventually replaced the common-law descent rules in England (beginning with the Inheritance Act 1833) and in American states, which largely abandoned the old canons early in the nineteenth century.
Researchers working in colonial and early American property records, probate proceedings, or treatise literature before roughly 1850 will encounter this term in discussions of which heir takes when a descent is traced. The doctrine required courts to identify the first purchaser to determine the correct line of descent — a question that could affect whether an estate passed to paternal or maternal heirs.
The term also appears in Norman French legal sources referenced in English common law commentary, where the first purchaser was called the "conqueror" or "conquereur" — a usage entirely unrelated to military conquest and instead reflecting the Norman concept of acquiring something by one's own act. Researchers in Anglo-Norman or early English legal history should be aware of this terminological overlap.
In American sources, the term largely disappears from operative legal doctrine after state descent statutes were codified, but it persists in treatises and commentaries that continued to explain the English common-law background. Finding the term in a twentieth-century American source likely indicates a historical or comparative discussion rather than a live doctrinal one.
The absence of case law citations in most historical definitions reflects how the concept worked in practice: it was a background rule absorbed into common-law reasoning rather than a frequently litigated point in its own right.

Historical Dictionary Support
The four source dictionaries are in strong agreement on the core meaning: the first purchaser is the ancestor who first brought an estate into a family by any means other than descent. All four anchor the definition to Blackstone's Commentaries, Book II, Chapter 14 — the foundational locus for this concept in English legal literature.
Burrill adds the most texture, noting the Norman French terminology ("conqueror" or "conquereur") and citing both Blackstone and Stephen's Commentaries. Burrill's reference to the "Grand Coutumier" (the customary law of Normandy) is a useful pointer for researchers tracing the historical roots of common-law descent doctrine into its continental antecedents.
Rapalje & Lawrence's entry is the most compressed, directing readers to a broader treatment under the heading DESCENT. That cross-reference is worth following in the original source for fuller context on how the first purchaser concept fit into the overall framework of descent rules.
None of the historical dictionaries address the post-reform period or flag the term's declining relevance after the nineteenth-century statutory changes. Researchers should not assume from the confident tone of these entries that the doctrine remained operative in their own era.

Jurisdictional Note
The first purchaser doctrine is native to English common law and followed common-law jurisdictions in their early periods. American states that received English common law at independence applied the concept, but most quickly departed from the underlying canons of descent through legislation. The doctrine has no meaningful modern operative role in U.S. jurisdictions. Scottish law and civil-law jurisdictions followed different descent frameworks and did not share this concept.
