Pedro Alfonso de León
Leonese noble and 14th Grand Master of the Order of Santiago

Pedro Alfonso de León (c. 1196 – 1226) was a Leonese Spanish noble of the House of Burgundy. He was, according to many historians, the illegitimate son of Alfonso IX of León. He was elected Grand Master of the Order of Santiago in 1225, succeeding Fernán Pérez Chacín in the role.
Biography

Still other historians have cast doubt on Pedro Alfonso's status as Alfonso IX's illegitimate son, that he existed at all or that he was a Grand Master of the Order of Santiago.
Marriage and descendancy
The name of his wife is not known, and historians disagree over whether Pedro Alfonso had one or two children. His children were as follows.
