Related question: when did the Salem witch trials become 'common knowledge' in America, for lack of a better term, and why the Salem witch trials as opposed to any other sort of tale of hysteria/superstition gone awry?

"Living memory" means a time which can still be recalled by people who are still alive.

The events of the American Revolution were a good 80 plus years after the Salem Witch Trials. There were people that old who participated in the Revolution - Captain Samuel Whittemore was born circa 1695, bayoneted multiple times at the Battle of Concord, and survived another 18 years. Anyone who alive during the Salem Witch trials and Revolution would have been very young during the former and very old during the latter. The latest-lived participant in the Salem Trials that I can find is Elizabeth Parris, one of the accusers, who died in Concord at age 77 in 1760.

As far as the Founders go, they were born much later after the Salem Trials. Benjamin Franklin is generally considered one of the oldest Founders, and was born in 1706. Of course, growing up in Boston he does have a connection to a prominent observer of the Salem events, namely in his relationship with Reverend Cotton Mather. Franklin as a teenager wrote a number of anonymous essays mocking Mather and the Puritan establishment that were published in Franklin's brother's paper The Courant, and during the 1721 smallpx epidemic they both had a very public debate over the benefits of vaccination (Mather was for, Franklin was against). However Franklin did meet with and respect Mather's moral teachings, and wrote about how his (Franklin's) whacking of his head on a beam in Mather's house after disregarding Mather's advice to stoop down was a lesson in humility.

There doesn't seem to be any record of them discussing the Salem Trials, however.
