Welcome to Oakwood Cemetery in Allegan, Michigan.
"The National Society Daughters of the American Revolution was founded in 1890 to promote Historic Preservation, Education, and Patriotism across the United States." If you spend any time in cemeteries, you will see mention of the group. The posted coordinates will take you to a gate, with a plaque on it.
Take the date referenced, call it EFGH.
From that number, add H + E, call that J. Then subtract F - E, call that answer K.
Using the posted coordinates, to the north add .0GJ and to the west add .0GK.
