 These include a fine early 17th-century monument to the Anderson family, spiro-form carvings on the exterior of the Ogee window of possible Rosicrucian significance, and the unidentified tombstone of a crusading knight.It is possible that this is a memorial to Sir William Keith, a companion of Sir James Douglas on his campaign to take the heart of Robert the Bruce to the Holy Land.Upon the failure of that mission Keith brought back the heart of Bruce to Melrose Abbey, and the body of Douglas to St Bride's Church, Douglas.
