I thought Jamestown common store was the first colonial attempt at socialism (1607).
and this would not count what seems to be numerous partially successful attempts by native americans (eg cahokia collective land management, etc) well before jamestown.
also the article appears to presume that written documentation is a necessary prerequisite towards proving that a settlement attempted socialism— i am fairly certain that archaeologists would tend to disagree...
the chinese communists also tried pure socialism without success.

Yes. 80% of the original colonists died and the colony needed to be resettled in 1610 and 1618. In 1618, they introduced private property.
