Who establish plymouth colony and organize the first ? john winthrop, roger williams, anne hutchinson ,william bradford

From what I studied in my textbook it is none of these are correct, but the most reasonable choice is William Bradford, mainly because he was the Pilgrims leader at the time.

Hope this helps!

Primary sources are usually  more accurate and are written by someone who experienced it or witnessed it. secondary sources are those who heard of it after the fact that can lose details and or twist the event in a light that benefits them.
