Note 2 — Chapter VII
Reading edition
It may be worth while to point out that the suggested Welsh name for the wine is based on a mistaken etymology. The word "Swanbridge" has nothing to do with swans, but is from the Norse or Danish proper name Sweyn (Swegen, Swain or Svend). The narrow neck of land connecting the place, at low tide, with the island of Sully is the "bridge" or "brigg" forming the second half of the word. Norse names are common all along the south coast of Glamorgan.
