Another one which GK from the Classics list helped out on. The San Francisco Chronicle has a piece on condos in Rome and mentions the following, inter alia:

She and her husband, Roberto Lucchesi, and their two daughters moved in 2002 from a two-bedroom condominium to a small development that backs up to a lush pine forest reserve that once belonged to Roman philosopher Pliny the Elder.

This forest was a mystery to me, but GK pointed me to the park's official website, wherein we can read:

Moving away from the Severiana way, along the path that begins where a post indicating no. 16 is situated, the Villa can be reached in a short space of time (the villa is fenced-off and can be visited by appointment). A few metres after the gate, the remains of a Paleochristian basilica can be found. Continuing along the path, at the sides of the road, the peak of the villa's outer walls can be seen. A few metres further on, you come across a large clearing where the remains of the so-called Villa "of Plinius" (Plinius the Younger, to be precise) are located. In reality, recent studies have revealed that the residence in the 'Laurentino di Plinio' was situated south of the Vicus Augustanus, corresponding to the ruins of the second Villa inside the Castel Porziano Estate, whereas the first Villa inside the Castel Fusano Park, is to be attributed to the orator Ortensius, who lived between 114 and 50 BC.

So how did we go from the Elder to the Younger ... Again, GK finds a probable source/connection in a page at Caroline Lawrence's site:

One of these villas is described in loving detail by its owner, the famous Latin letter writer, Pliny the Younger. In the Roman Mysteries, I assume that Pliny the Younger inherited the villa from his uncle, the admiral and naturalist Gaius Plinius Secundus, also known as Pliny the Elder. One day, Flavia and her friends pay a short visit to the old admiral at this villa.

It seems to be a reasonable 'leap' ... or not.
