Chronicle of Abbot Ralph of Coggeshall
The Chronicle of Abbot Ralph of Coggeshall (Chronicon Anglicanum) is an indispensable medieval history that brings to life centuries of English and European affairs through the eyes of a learned Cistercian monk. Ralph of Coggeshall, abbot of the Abbey of Coggeshall in Essex in the early 13th century, continued and expanded his community’s chronicle, documenting events from the Norman Conquest of 1066 into the tumultuous reign of King Henry III. Blending eyewitness testimony, careful compilation, and the monastic commitment to record-keeping, this chronicle offers a rare narrative of political intrigue, royal power struggles, and social upheaval in England and beyond. Ralph’s work captures the reigns of pivotal figures such as Richard I and King John, providing invaluable insights into their characters, decisions, and the forces that shaped medieval rule. More than a simple annal, Chronicon Anglicanum conveys the texture of medieval life and governance, making it a rich source for scholars and readers fascinated by English history, monastic authorship, and the shaping of the medieval world.

COI 25% and Higher is in Coefficient of Inbreeding.
COI 25% and Higher. An individual who is the child of brother and sister, or father and daughter, or mother and son, or equivalent to.
The best known case of individuals with a COI higher than 25 is the five children of Philip IV King Spain and Mariana of Austria Queen Consort Spain who had a COI of 25.39% going back ten generations with fifty-three common ancestors (see study undertaken by the University of Santiago de Compostela in Jan 2010). Taking their ancestry back further to eighteen generations they have a COI of 25.89% with two hundred and sixty four common ancestors.
