[3] As an Oyster Bay Roosevelt, and through his ancestor Cornelius Van Schaack Jr., Elliott was a descendant of the Schuyler family.

He performed well academically though he soon had to withdraw and return home after unexpectedly falling ill.[6] Elliott maintained a charming and winsome personality all his life, which masked a growing drinking problem that started at a young age.

Once in Dallas, however, their plans changed after they met a group of other young men, one of whom was the sportsman Andrew Jameson, whose family made a fortune in Irish whiskey.

By mid-January, they were at a location just west of Graham, Texas where they listened to "the panther and wolves crying and howling" and kept their firearms within easy reach.

The party passed through Fort Griffin, Texas, where they found in abundance bison, deer, antelope, quail, wild turkeys, and rabbits.

[7] On February 3, Roosevelt entered into his diary: "[We] made our permanent camp at the bottom of a huge canyon by a fine water hole."

[7] On his father's death in 1878, Roosevelt inherited a fortune and lived the lifestyle of the idle rich by, among other pursuits, hunting tigers in India.

[9] The couple had three children: After this point, Elliott Sr. developed a "casual drinking" problem, which soon became alcoholism, an affliction to which his son Hall later succumbed.

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.

He was declared sane and mentally competent by two different courts, and thus Theodore Roosevelt failed to gain official conservatorship over his brother.

Elliott's drinking became worse as he became despondent over both the loss of his wife and son, and the fact he still wasn’t allowed to see his remaining children.

On August 13, 1894, the 34-year-old Roosevelt attempted suicide by jumping out a window; he survived the initial fall, but the following day he suffered a seizure and died that evening of heart failure.
