Robert de Romille (also de Rumilly) was an adventurer from Brittany who joined the Normans in their Conquest of Britain. After 1086 King William I made him lord of the estates of Bolton Abbey. Romille built the first Skipton Castle in 1090 to repel the expansions of Malcolm III of Scotland. In 1102 Romille's lands were greatly increased by Henry I of England to include all of upper Wharfedale and upper Airedale. His male line died out before 1310; but by his daughters he has many descendants today.
