Which of the following founding fathers had both of his parents buried
at Granary Cemetery?
A. Ben Franklin
B. John Hancock
C. Paul Revere
D. Samuel Adams

A. Ben Franklin

Explanation:

Both Benjamin Franklin and Samuel Adam’s parents are buried at Granary Cemetery. However, Franklin's parents are more famous, and the guides and information about the cemetery always mentioned that his family is buried at the Granary Burying grounds. Franklin's family has the whole tomb at the cemetery, marked with the obelisk. Therefore, both Josiah Franklin and Abiah Lee Folger Franklin, Benjamin’s parents, are buried here, even though Franklin himself is buried in Philadelphia, at Christ Church Burial Ground. There were even attempts to rename Granary burying ground to  "Franklin Cemetery".

Paul Revere’s parents are both buried here as well, but this answer is incorrect as he was not the founding father.
