March ab Meirchion

   March ab Meirchion or the King Mark of the Romances was a prince whose territory is said to have been in Cornwall. The romances have painted him in a poor light but by reading between the lines, we see that he was an important personage in the Arthurian realm. As one of the chief merchant or naval princes, his position ensured that Arthur would support him in the problems associated with an unruly nephew and an errant wife. You could say that March was particularly unfortunate in having such a nephew as Trystan, and such a wife as Essyllt, the Sir Tristrem and Yseult La Belle of the French Trouveres.
