Definition
Brechinia is a historical Latin place-name used in legal and ecclesiastical records to designate the region or lordship of Brecon, located in what is now Powys, south-central Wales. The term appears primarily in medieval Latin documents — charters, writs, patent rolls, and ecclesiastical instruments — where it served as the Latinized form of the Welsh toponym. It carries no independent legal meaning as a term of art; its significance is purely locative, identifying the jurisdiction, lordship, or diocese to which a document, grant, or proceeding pertained.

Why It Matters in Research
Researchers encountering Brechinia in primary sources should treat it as a jurisdictional marker, not a legal concept. Its appearance in a document signals that the instrument originates from, or concerns property or persons within, the lordship or later county of Brecon (Brecknockshire). Several navigation points are worth noting.
First, the term is orthographically unstable in medieval sources. Variant spellings — Breconia, Brechonia, Breconiashire, and anglicized forms such as Brecknock or Brecon — appear interchangeably depending on the scribe, period, and document type. A search limited to one spelling will miss relevant instruments.
Second, Brechinia sits at the intersection of Welsh Marcher law and English common law, which creates research complexity. The lordship of Brecon was a Marcher lordship, meaning it operated under the authority of its lord rather than the English crown's ordinary writs for a significant portion of the medieval period. Documents from this region before the Laws in Wales Acts (1535–1542) may reflect Marcher legal customs rather than standard common law procedure. After those Acts, Brecknockshire was formally incorporated into the English county system, and subsequent documents use the anglicized county name rather than the Latin Brechinia.
Third, ecclesiastical records present a separate line of usage. Brecon lay within the Diocese of St. David's, and Latin instruments from that see may use Brechinia when describing parish, prebend, or chapter matters. Researchers working on Welsh church history or tithe disputes should check both the secular and ecclesiastical documentary streams.
Fourth, when Burrill's Law Dictionary references Brechinia, it does so in a purely geographical-lexicographic context, as part of a series of place-name entries glossing Latin topographical terms used in English legal records. The entry is a finding aid for deciphering historical instruments, not a substantive legal definition.

Historical Dictionary Support
Burrill's Law Dictionary treats Brechinia as a geographical entry, grouping it with other Latinized place-names that appeared in English and Welsh legal records. Burrill's entry is fragmentary as preserved — the surrounding text references Camboricum and bridge, suggesting the entry appeared in a sequential place-name glossary rather than as a standalone legal term. This is consistent with Burrill's broader method of including Latin topographical terms that a practitioner or court officer might encounter when reading old writs, charters, or rolls.
No other standard historical legal dictionaries — not Bouvier, not Black's early editions, not Jacob's Law Dictionary — carry a substantive entry for Brechinia. Its absence from those sources reflects the term's status as a locative rather than a term of legal art. Researchers should not expect doctrinal content from any historical dictionary entry on this term; the dictionaries are functioning as Latin-to-English geographical glossaries when they include it.

Jurisdictional Note
Brechinia refers specifically to the Welsh region of Brecon and has no application outside of records pertaining to Wales or the Welsh Marches. After 1536, English legal instruments use Brecknockshire as the county designation. The term Brechinia is effectively confined to pre-Tudor and ecclesiastical Latin sources.
