Nicholas's ties to his mentor, Jefferson, continued later in their lives. Jefferson stopped at Nicholas's house, called Mount Warren, on his trips back and forth to Poplar Forest.1 His daughter Jane married Jefferson's grandson Thomas Jefferson Randolph in 1815. Nicholas and his brother George were heavy land speculators and as a consequence of the Panic of 1819, he defaulted on a $20,000 note, which had been cosigned by Thomas Jefferson. Jefferson was left with the responsibility for repaying the debt, worsening his own economic situation. Nicholas died the following year, and was buried in the Jefferson family graveyard.
