Answer:
It would be necessary to have access to primary sources such as Nataniel Bacons' diaries, as well as letters or other documents made by him.
Step-by-step explanation:
A primary source is a document that depicts events (or talks about a person) and that was created at the time that these events are happening. Thus, if an individual wishes to help, with the search for sources, another person who is making allegations about a film by Nathaniel Bacons, that individual must look for documents made by Bacons himself who attest to the statements mentioned or disprove them. For that, letters, diaries, tickets, essays or any other document created by Bacons would be needed.
