The area offered various leisure activities such as swimming in the local springs, fishing, and hunting quail, deer, and alligator.

DeBary turned his leisure site into a profitable enterprise when he planted over 600 acres (2.4 km2) of citrus trees and began a steamboat company for trade up the St. John’s River to Jacksonville.

Guests to DeBary Hall may have included Presidents Grant and Cleveland, European Royalty, and General William Tecumseh Sherman.

The 8,000 sq ft (740 m2) hunting lodge included an elevator for guests’ luggage, running water through a 500-gallon tank in the ceiling, wall-fed electricity made onsite by natural gas, a wired call system throughout the entire house, and a lightning protection system that covered the roof of this amazingly advanced home.

The unique architectural features of the home serve as the main significance for the National Register of Historic Places designation.

As a young man, Frederick befriended G. H. Mumm, whose family produced brands of champagne in Rheims.

DeBary Hall served as an active hunting and fishing preserve during the mild Florida winters.

Eugenie moved to Germany with her husband Baron Hugo Von Mauch before her ninetieth birthday.

Leonie and Adolphe were minors when their grandfather died, and the deBary estate was placed in a trust for them guarded by their father Cecil Lyon.

His sister Leonie became the sole owner of DeBary Hall with her husband, Benjamin Brewster, a childhood friend.

Leonie made more renovations to the family home than any previous owner including putting in a tennis court, new flooring, and a larger bathroom in the Master Suite.

The Paco Land Company in turn sold a portion of the property to George Stedronsky, a Northerner with hopes of creating a retirement community in Florida.

In late 1947, Mr. Stedronsky sold his plans to Plantation Estates, Incorporated, a land developing firm.

DeBary Hall became part of "Plantation Estates" and much of the surrounding land became individual lots with small houses.

The Florida Board of Parks and Historic Memorials acquired the Hall and erected a bronze plaque on the front lawn.

The site continues to win preservation, educational, and interpretive awards at the local, state, and national level.

In 2008, DeBary Hall Historic Site received the National Association of Counties Achievement Award.

In 2007, the stable restoration was completed and acknowledged with a Florida Trust for Historic Preservation, Outstanding Achievement in Adaptive Reuse award.

Modern structures added to the site include a Visitor’s Center with a gift shop, trail-head pavilions, and an Imagidome Theater.

The design and construction of the pavilion and theater follow former outbuildings on the site based on historic photographs.

The bike trails run over 10 miles (16 km) to Gemini Springs and Lake Monroe Park.
