Leonel Power
British composer and music theoretician

Leonel Power (also spelled Lionel, Lyonel, Leonellus, Leonelle; Polbero), c. 1380–1445, was an English composer of the early Renaissance. Along with John Dunstaple he was a dominant figure of 15th-century English music. Mainly a composer of motets and of sections of the Mass, he is the best-represented contributor in the Old Hall Manuscript. Occasionally he is referred to by his Christian name only.
Life and career
Very little is known about Power's life. Documents dating from the early 1440s refer to him as a native of Kent. Stylistic analysis of his music, as well as his probable age during his known appointments, show that he may have been born between 1370 and 1385. A suggestion that Power was of Irish origin, which appeared in W.H.G. Flood's 1905 A History of Irish Music, is usually discounted by modern scholars, since Flood is not known to have had any other sources on Power's life than are currently available.
The earliest dated reference to Power refers to him as instructor to the choristers of the household chapel of Thomas of Lancaster, 1st Duke of Clarence.

Why this record matters
“Leonel Power” is worth following because a concise public description often conceals a longer documentary argument. Here, Leonel, Power and British provides the most credible route into that argument.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Nov 2, 2024. The linked authority identifier is Q2711953. VIAF identifies the subject as 79169248. The Library of Congress control number is n83198286. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1380, 1445, 1370 and 1385.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
