The booklet Mourt’s Relation (full title: A Relation or Journal of the Beginning and Proceedings of the English Plantation Settled at Plimoth in New England) was written primarily by Edward Winslow, although William Bradford appears to have written most of the first section. It was written between November 1620 and November 1621 and describes in detail what happened from the landing of the Mayflower Pilgrims on Cape Cod in Provincetown Harbor through their exploring and eventual settling of Plymouth Colony. The book describes their relations with the surrounding Native Americans, up to what is commonly called the first Thanksgiving and the arrival of the ship Fortune in November 1621. Mourt’s Relation was first published and sold by John Bellamy in Londonin 1622. This significant tract has often been erroneously cited as “by George Morton, sometimes called George Mourt” (hence the title Mourt’s Relation).
The booklet was summarized by other publications without the now-familiar Thanksgiving story, but the original booklet appeared to be lost or forgotten by the eighteenth century. A copy was rediscovered in Philadelphia in 1820, with the first full reprinting in 1841. (Wikipedia)
