Sir Marmaduke de Thweng
Robert's son, Sir Marmaduke de Thwent, married Lucia de Brus, and when the Bruce inheritance was partitioned among the sisters of Peter, the last male representative of that family, Marmaduke, gained many valuable additions to his possessions, in the right of his wife. One of the chief additions was the old de Brus castle of Danby (now Castleton), and much land in that part of Cleveland. Lucia de Thweng, the daughter of Sir Robert Marmaduke's eldest son, was one of the end of most notorious young ladies that this part of the world produced in the Middle Ages. Married much against her wishes at the age of 16, to William le Latimer, she was soon divorced from him on the grounds of adultery with Niclolas de Metnell of Whorlton Castle, by whom she had a son. She also lived some time with her cousin, Marmadudke de Thweng, of Kilton Castle, and subsequently married Robert de Eveoingham and later Bartholomew de Fanacourt. She died in 1346, aged 67, a considerable age in those days especially when her somewhat hectic life is taken into consideration.
Founded a Charity
In 1374 Thomas, the fourth Lord Thweng, of Thweng and Kilton died and with him the direct line of Thwengs ceased. He was a priest and the fourth son of Marmaduke, first Lord Thweng of Thweng and Kilton. Most of his time was spent at Kirjleatham, of which church he was the parson. He it was who founded a chantry there to pray for the souls of his ancestors, his own soul, and those of the overlords of Kilton and the king and queen. As a result of the marriage in 1298 of Lucia de Thweng and Robert de Lumley the Kilton property now passed into that family. With various changes the de Thweng estates seem to have remained in the hands of the Lumleys until the seventeenth century, when we again find Thwengs holding land in Kilton, but whether they were living at the Castle or not is not at all clear. Popular tradition tells us that Cromwell destroyed it but there are good reasons for believing that it was abandoned by the Lumleys, and that its present ruinous condition is due more to time, weather and vadalism than the cannons of the Protector.
