Not a good doc

For example, its suggestion that Benjamin Franklin's connection to the Hellfire Club is largely based on anecdotal evidence and historical speculation rather than definitive documentation.

Letters and Writings: Some of Franklin's letters mention clubs and societies that have a reputation for debauchery, which has led to speculation about his visits to such gatherings.

Contemporaneous Accounts: Some of Franklin's contemporaries referenced the Hellfire Club and its activities, and Franklin's reputation as a man of wit and social engagement lends credence to the idea that he may have encountered such groups.

Cultural Context: Franklin was known for his interest in various social clubs, scientific societies, and intellectual gatherings, which aligns with the type of organization the Hellfire Club represented.

Historians' Interpretations: Some historians have suggested that Franklin's philosophical leanings and his openness to unconventional ideas might have drawn him to the Hellfire Club, but this remains largely speculative.

Conclusion
While there are intriguing connections and circumstantial evidence suggesting that Franklin may have had some contact with the Hellfire Club, there is no concrete proof of his membership or attendance. Most claims stem from interpretations of his character and the social context of his time.
