I'd like to confirm the Pressley's (with 2 s's) abode in Louisville.
Mr. Pressley bought my aunt and uncle's house on Beaver Street off Bluegrass Avenue in the south end--near Churchill Downs. That was in the early 50's.
My late mother-in-law, Vera Vonsick, was Mrs. Pressley's hair dresser until her death shortly after Elvis gave up the oxygen habit.
Mrs. P shared many stories of her famous grandson's late nite visits....always secretive and seldom announced even to grandma and grandma. Of course, owning one's own private jet and being only a few minutes from the airport made the visits easier than you might expect.
My uncle who owned the property that he sold to the Pressley's was Hubert Brent. I was in that house many times as a youngster.
