On his father's death in 1878, Roosevelt inherited a fortune and lived the life-style of the idle rich by, among other pursuits, hunting tigers in India.

On October 27, 1880, Elliott was Theodore's best man at Theodore's first marriage to Alice Hathaway Lee.
In 1883, Roosevelt wed a rich debutante, Anna Rebecca Hall (1863–1892), the eldest daughter of Valentine Gill Hall Jr., and Mary Livingston Ludlow.
The wedding was held on December 1, 1883 in Calvary Church in New York City.
The couple had three children:
Anna Eleanor Roosevelt (October 11, 1884 – November 7, 1962), called Eleanor
Elliott Bulloch Roosevelt Jr. (September 29, 1889 – May 25, 1893), who died from scarlet fever
Gracie Hall Roosevelt (June 28, 1891 – September 25, 1941), called Hall
After this point, Elliott Sr.
developed a "casual drinking" problem, which soon became alcoholism, an affliction to which his son Hall later succumbed.

Due to his drinking problem, Elliott was exiled to Abingdon, Virginia, where he constantly wrote letters, mostly to Eleanor.
Eleanor later recalled that on his many horseback riding expeditions with the young children in Virginia, he became attached to "one girl in particular of whom I was jealous."
On occasion, he would, to the jubilation of Eleanor, return home for a few days.
Theodore Roosevelt became the conservator for his spendthrift brother.

Elliott fathered a son with Catherine "Katy" Mann (1862–1941), a young servant girl employed by Anna.
His brother sent a detective who specialized in likenesses to look at the child and subsequently the Roosevelts settled out of court for $10,000.
The sum was placed in a trust, but according to the Manns the child never received a dime as the money apparently was looted by Katy's lawyers.
There was some correspondence between Eleanor Roosevelt and her half-brother Elliott Roosevelt Mann (c. 1891–1976).

In 1894 the 34 year-old Roosevelt attempted suicide by jumping out a window; he survived the initial fall, but suffered a seizure and died a few days later.
At the time of his death, his alcoholism had escalated such that he was consuming numerous bottles of champagne and brandy each day.
