For First Thanksgiving?

Most of that is believed to have happened or is so cloaked in mythos that any version is likely to be true if you're talking the American version.

Source, native. The women being there is the thing that's least likely to be true.

Nearly all of what historians have learned about one of the first Thanksgiving comes from a single eyewitness report: a letter written in December 1621 by Edward Winslow, one of the 100 or so people who sailed from England aboard the Mayflower in 1620 and founded Plymouth Colony in Massachusetts. William Bradford, Plymouth’s governor in 1621, wrote briefly of the event in Of Plymouth Plantation, his history of the colony, but that was more than 20 years after the feast itself.
