Sir Alexander Ramsey of Dalhousie, Sheriff of Tevitdale
Legend tales of the Sheriff of Teviotdale who upon visiting Hermitage Castle, was captured and thrown into the dungeon where, unfed, he died a slow painful death around the mid 14th century. Legend dictates that in early 19th century a mason broke into the sealed up dungeon and found the remains of a knight still with sword in hand and accordingly on quiet nights his groans and screams can still be heard breaking the silence.
William II de Soules, Lord of Liddesdale and Butler of Scotland
Scottish folklore maintains that de Soulis was involved with the Black Arts and had a familiar called Robin Redcap (Type of evil Goblin according to Scottish Border mythology), that went around capturing local children and imprisoning them within the castle's dungeon. Apparently the locals, eventual captured the Lord and after wrapping him in lead, boiled him alive at a nearby stone circle; Nine Stane Rigg. The cries of his little victims can still be heard as a reminder, in and around the castle.
Historical facts might suggest this was slander placed about him, by others in the court of Robert the Bruce and that in reality he died in Dumbarton Castle after confessing to treason against the Scottish ruler.
Mary, Queen of Scots
Legend tales of a ghost that floats around the castle wearing a beautiful white dress, which some claim to be Mary, Queen of Scots who is known to have visited Hermitage Castle for a brief stay.
