Here's the Grove entry.
Pacheco y Basanta, José
(b Mondoñedo, 15 Dec 1784; d Mondoñedo, 23 March 1865). Spanish composer. He joined the choir of Mondoñedo Cathedral in 1795, and, after his voice broke became organist there while studying composition. His first public appearance took place at Christmas 1804, when he directed some villancicos he had composed himself for the festivities; from that time onwards, he was put in charge of the care and education of the choirboys, and in 1806 he was formally appointed maestro de capilla. Most of Pacheco's professional activities took place at the heart of Mondoñedo Cathedral. He received offers to transfer to Lugo, in 1817, and to Oviedo, in 1833, and also competed, unsuccessfully, for the directorship of Santiago de Compostela.
I've created this page
http://imslp.org/wiki/Category:Pacheco_ ... _Jos%C3%A9
and cited on it the Grove article according to their MLA standard. The way they break the name seems strange, but I don't doubt they are right so you may have to rename that page I made.
