More was 6 when the "Mayflower" landed at Plymouth Colony. When he stepped on land, he worked with all of the others to help gather supplies for food and shelter and to bury the dead. In the spring of 1621, he attended the first Thanksgiving. Nothing is known of More during the years he lived with the Brewster family from 1620 to 1627, except that his name is on a document giving adults cattle and other livestock.
