** His remains were first interred in the public vault at the Congressional Cemetery in Washington, D.C., on February 21, 1863. His remains were later removed to Trinity Church in Manhattan, New York City. This is where his father, Richard Woodhull, and mother are buried.
** The Arlington National Cemetery site has this to say about the Woodhull Memorial Flagstaff:
It is 90 feet tall and on the south lawn of the Memorial Amphitheater, one of only two flagpoles at Arlington National Cemetery. It was erected in 1924 and dedicated to Cmdr. Maxwell Woodhull, USN, 1813-1863.
** The Civil War Navy Sesquicentennial site has a lot about Woodhull's reports of operations on the St. John's River in Florida.
