Here is a blog post about it, which requires a barf alert:
The author of the blog post is an in-law of a descendant of N. Grigsby, the person over whose remains this gravestone stands. She repeats lies about the Republican party being racists that Dinesh d’Souza has researched and refuted in his recent book and movie Hlllary’s America.
Thanks. That woman just writing her own history. Believe it or not, my government professor in college was peddling that same story about the republicans being former racist democrats.
