Aminadap, Aminadab
One of the early kings of Corbenic (Carbonek), the Grail Castle, in the Vulgate Estoire del Saint Graal. His father was Joshua, king of Terre Foraine (Strange Land), son of Bron. He married the daughter of the British king Lucius, and his son, Carcelois, (Castellors) reigned after him.
His descendants included Pelles, Elaine, and Galahad. John of Glastonbury names him as a maternal ancestor of Arthur.
The name is found in Exodus 6:23 as the father-in-law of Aaron.
