Graceland is obviously significant to the Presley family history -- it was home to Elvis Presleybefore he died on the property in 1977. Family members including Lisa Marie's son Benjamin Keough, her grandparents, Vernon and Gladys Presley, as well as Elvis’ grandmother, Minnie Mae, have also been buried there.
Graceland has also served as a backdrop for other family celebrations over the years -- including what would have been Elvis' 80th birthday in 2015 -- and a vigil to honor Elvis on the 40th anniversary of his death in 2017.
As for Lisa Marie's service, the announcement also notes, "In lieu of flowers, the family encourages all who wish to send something to do so in the form of a donation to The Elvis Presley Charitable Foundation."
The foundation is known to support different orgs, focusing on arts, education, and children's programs in the Memphis area.
