I want to know the answer to the following question:
Who was Roger Williams?
All the background I'm provided with is that "The phrase "[A] hedge or wall of separation between the garden of the church and the wilderness of the world" was first used by Baptist theologian Roger Williams, the founder of the colony of Rhode Island, in his 1644 book The Bloody Tenent of Persecution.". Is that enough to answer the question?
Answer: yes
