Roger de Busli (c. 1038 – c. 1099) was a Norman baron who participated in the conquest of England in 1066.
[2] By the time of the Domesday survey de Busli was tenant-in-chief of 86 manors in Nottinghamshire, 46 in Yorkshire, and others in Derbyshire, Lincolnshire and Leicestershire, plus one in Devon.
[4] The de Buslis had one son, also called Roger, who died as an infant, thus leaving no heirs.
[5] His daughter (or possibly his sister) Beatrix, (also known as Beatrice de Builli), married William, Count of Eu.
His lands were given to Robert de Bellême, who lost them in 1102 after he led a rebellion against Henry I of England.
