El Dorado is at Sunnyside where the Stivenders built.  The railroad ran thru and there were docks where the boats brought oranges and other items to be shipped out.

 

Arthur Abrehart Stivender
Arthur A. Stivender came to Leesburg in 1861 with his mother [Margaret Gillie Ann Lee] and siblings after his father [Duncan Wright Stivender] died.  He settled at El Dorado, Sunyside, where he built his home in 1885.

 Three miles from Leesburg, to the east, are Eldorado and Sunnyside. At Eldorado, one of the first groves developed was a small island, on which was a wild grove. Mr. J. R. Cunningham, of Alabama, bought it and budded it to sweet oranges — the buds coming from a tree growing on a mound underlaid with marl, on Col. Thos. C. Lanier's place. Mr. Cunningham had eaten fruit from that tree, which was very delicious. The soil on his island grove was peculiarly suited to the production of fine quality fruit and it became known as the Cunningham orange and was extensively budded in the Leesburg section. It was with fruit from that grove that Major O. P. Rooks took first premium at the New Orleans fair in the Eighties.  It is from the reputation of the fruit from that grove that the "Cunningham Sweet" was brought out as a trade name. Like many other varieties, the Cunningham orange on other soils was not the Cunningham orange of the Eldorado grove.
 Dr. Arthur Stivender developed a famous wild grove at Eldorado, which is still owned and managed by his widow, whose father was also an early developer there. Col. W. H. Sims, one time Lieutenant Governor of Mississippi and Assistant Secretary of the Interior under Hoke Smith, owned a fine natural grove there, as did Mr. Kidd, of Cincinnati.  Mrs. Thos. C. Platt, of New York, wife of the noted Republican boss, became owner of a beautiful natural grove at Eldorado, which was sold a few years ago to Mr. Emmons, of Kansas City, and which at his death passed to his niece, Mrs. Lyle.
 A short distance away is Sunnyside. Judge W. A. Hocker, of Virginia, came to Sumter County in the Seventies, taught school, and bought at Sunnyside, setting out a grove there and living on it. He opened an office in Leesburg where he practiced law in partnership with Judge Milton H. Mabry. Both these distinguished gentlemen sat on the Supreme Bench of Florida. The Hocker grove is now owned by Mrs. Manley, of Sebring, who bought it of our distinguished fellow citizen, Major Robert Wood, of Virginia. Mr. T. S. Johnson was an early settler from Cincinnati, as were Mr. Mclntyre of Chicago, Mr. Albright of Iowa, and Mr. Henshaw of Cincinnati, all making valuable groves which still remain so at Sunnyside.

 

From p. 121.  The fruit from the shores of Lake Harris was boated to Eldorado for the Seaboard [railroad].
