Definition
A historical ecclesiastical rate — a small customary payment made in certain localities as a substitute for, or in satisfaction of, the tithe owed on fat beasts, oxen, and other unfruitful cattle. "Unfruitful cattle" refers to animals that do not produce offspring or secondary goods (such as milk) and were therefore not subject to the ordinary predial or mixed tithe on produce; the growth halfpenny served as an agreed local commutation for the titheable value of such animals.
The payment reflects the medieval English system of tithes, in which the Church was entitled to a tenth of the increase or produce of land and livestock. Where livestock yielded no separable "increase" amenable to ordinary tithe assessment, local custom in some parishes substituted a fixed money payment — the growth halfpenny — in its place.
Why It Matters in Research
This term is nearly exclusively relevant to historical ecclesiastical law research and disputes arising from tithe liability in pre-Tithe Commutation Act England. Researchers encounter it most often in records of ecclesiastical court proceedings, terriers (parish inventories of titheable property), and local customary law compilations. Several practical research notes apply:
First, the term is narrowly local. Not all parishes levied a growth halfpenny; its existence depended entirely on established local custom. Any research involving this term must anchor to a specific parish's records or a documented local custom — the term cannot be generalized across English ecclesiastical law without geographic qualification.
Second, the reference in both Rapalje & Lawrence and Bouvier to "Clayt. 92" points to Clayton's Reportes — a seventeenth-century English reports compilation. Researchers relying on that source should verify the edition and confirm the passage, as Clayton is not among the most widely indexed historical reporters and citation accuracy in secondary legal dictionaries of this era was variable.
Third, following the Tithe Commutation Act 1836 (6 & 7 Will. 4, c. 71), most surviving tithe obligations in England and Wales were converted to rent charges and mapped in tithe apportionments. Growth halfpenny obligations, if still operative at that date, would have been subsumed into or addressed by that commutation process. The tithe apportionment records held at The National Archives (and in county record offices) are the practical endpoint for tracing whether a specific growth halfpenny obligation survived into the nineteenth century.
Fourth, American researchers should note that Bouvier's inclusion of this term reflects his encyclopedic approach to inherited English legal vocabulary rather than any American legal practice. The tithe system as such was never adopted in American law, and the growth halfpenny has no operational counterpart in any U.S. jurisdiction.
Historical Dictionary Support
Rapalje & Lawrence and Bouvier's Law Dictionary are in exact agreement, reproducing the same single-sentence definition and identical citation. This verbatim convergence is common for obscure ecclesiastical terms where both dictionaries drew from the same limited English antecedents. Neither source elaborates on the rate's amount, the mechanism for its assessment, or the range of parishes in which it was known to apply — significant gaps for any researcher needing operational detail.
The definition's framing of "unfruitful cattle" as the relevant category is legally meaningful: it distinguishes the growth halfpenny from the ordinary tithe on increase (such as young animals or wool), situating it instead as a payment for animals valued as stock or for slaughter rather than for ongoing production. Neither dictionary addresses how "growth" in this context relates to the broader tithe vocabulary of "small tithes," "mixed tithes," or "personal tithes," leaving the term's precise taxonomic place in tithe law undeveloped.
Jurisdictional Note
The growth halfpenny is a term of English ecclesiastical and customary law only. It has no recognized equivalent in Scottish, Irish, or American legal systems. Within England, its application was parish-specific, governed by local custom rather than national statute.
