Lettow
Lettow was a by-name given to a few Pomeranian nobles from a noble family from Vorbeck who went to assist Algirdas and Vytautas, the Great Dukes of Lithuania, in the 14th century. Lettow meant "Lithuania" in the Saxon language, and it appears in the General Prologue to The Canterbury Tales, wherein it is said of the Knight, a veteran of the Baltic Crusades: "Ful ofte tyme he hadde the bord bigonne / Aboven alle nacions in Pruce; / In Lettow hadde he reysed, and in Ruce, / No Cristen man so ofte of his degree." With a few variants like Lettau, Lettaw, Litav, Littauer or Littawer, it was also adopted by some other Vorbe(c)ks in Pomerania as a surname.
