The monument was dedicated October 6, 1937 by the Thomas Lloyd Memorial Association, an organization mainly consisting of Lloyd descendents and state/local history buffs.

(NOTE: The inscription contains inaccuracies; it includes information about a different Thomas Lloyd, who was from New Hanover County, NC.)
There is a pamphlet that was printed regarding the monument's erection and dedication, but alas I can not find a copy (is it the 1941 version? I don't know).
