In September 1844, Delano was married to heiress Laura Eugenia Astor. Laura was a daughter of
William Backhouse Astor Sr. and Margaret (née Armstrong) Astor, and a sister of, among others,
John Jacob Astor III and
William Backhouse Astor Jr. (husband of
the Mrs. Astor). Reportedly, Laura was the favorite granddaughter of
John Jacob Astor, the founding
Astor family patriarch and America's first millionaire who died in 1848, four years after their marriage. Her maternal grandparents were
John Armstrong Jr. (a
U.S. Senator,
U.S. Minister to France under
Thomas Jefferson and
U.S. Secretary of War under
James Madison) and Alida (née
Livingston) Armstrong. In New York City, the Delanos lived at 190
Madison Avenue. Franklin Delano was a member of the
Union Club (which he joined in 1839, three years after its founding in 1836), the
Knickerbocker Club, the
Century Club, the
New-England Society, and the
American Geographic Society. His widow died in 1902.
Steen Valeitje As a wedding gift, Laura's father gifted the couple the southernmost 100 acres of his
Rokeby estate. The estate came to be known as "Steen Valetje" (which means "little stone valley" in Dutch). The Tuscan-style mansion, designed by
Frank Wills, was completed in 1851. In 1866, William Astor Sr. conveyed the adjoining 142 acres of Rokeby to his son, Henry. Henry Astor built a brick dwelling on this land, but in 1873, conveyed the property to Laura, thus expanding "Steen Valetje". A gatehouse, designed by
William Schickel & Co. was added in 1874. The mansion was expanded in 1881 by architect
Thomas Stent. The Astors and the Delanos commissioned German-born landscape gardener Hans Jacob Ehlers to improve the grounds at Rokeby and Steen Valetje. Ehlers converted an old farm track into a woodland path called the Poet's Walk in honor of poets
Washington Irving and
Fitz-Greene Halleck, who are said to have strolled there. It is now
Poets' Walk Park, managed by the not-for-profit
Scenic Hudson. As Delano and his wife both died childless, he left Steen Valetje to his nephew, coal baron Warren Delano IV. Jennie Walters Delano, Warren IV's wife, died two years later in 1922. Their son Lyman inherited "Steen Valetje," remodeled it in the Georgian style and renamed it "Mandara"; his family kept the home until 1967 when it was sold to financier William Stix Wasserman. ==Notes==
