Baron Butler
extinct barony in the Peerage of the United Kingdom
The title Baron Butler was created in the Peerage of England in 1666.
The Butler family have several branches (Irish: Buitléar) who descended from Irish-Norman dynasties, all of which descended from Theobald Walter who was Chief Butler of England.
History of the title
Baron Butler of Moore Park, Co. Hertford, was created in the Peerage of England in 1666, for Thomas Butler, 6th Earl of Ossory (the eldest son of the 1st Duke of Ormonde). Four years previously, he had been called up to the Irish House of Lords by a writ of acceleration as the Earl of Ossory. As the Baron predeceased his father, his son James inherited the barony in 1680 and then the dukedom in 1688. However, in 1715 his English titles were attainted because of his part in the Jacobite rising. The title was able to pass through the female line and in 1871, the attainder was reversed for the great-great-great-great-grand-nephew of the second duke, the 7th Earl Cowper. Lord Cowper died childless, however, and the title has been abeyant since 1905.

Why this record matters
The subject matters to the general reference register because the source frames it as extinct barony in the Peerage of the United Kingdom. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 9, 2025. The linked authority identifier is Q4862213. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1666, 1680, 1688 and 1715.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
