The Castle Dairy implies a connection to which medieval fortification to the east of the town of Kendal, Cumbria, in northern England?
Kendal Castle Kendal Castle is a medieval fortification to the east of the town of Kendal, Cumbria, in northern England. The castle, which is atop a glacial drumlin, was built in the 12th century as the  Caput baroniae for the Barony of Kendal. By the 15th century, the Parr family owned the castle. Queen Catherine Parr  was once thought to have been born at the castle; however, modern research has shown that it was in great disrepair by the 16th century and she was most likely born in Blackfriars, London.
Tintagel Castle Tintagel Castle (Cornish: Dintagel , meaning "fort of the constriction") is a medieval fortification located on the peninsula of Tintagel Island adjacent to the village of Tintagel, North Cornwall in the United Kingdom. The site was possibly occupied in the Romano-British period, as an array of artefacts dating to this period have been found on the peninsula, but as yet no Roman era structure has been proven to have existed there. It subsequently saw settlement during the Early Medieval period, when it was probably one of the seasonal residences of the regional king of Dumnonia. A castle was built on the site by Richard, 1st Earl of Cornwall in the 13th century, during the Later Medieval period. It later fell into disrepair and ruin.
