The answer - one. George W. Bush, the 42nd President of the United States, is the only former POTUS to have a set of twin offspring. Fraternal twins Barbara Pierce Bush and Jenna Welch Bush were born to the future President and future First Lady Laura Bush on 25 November 1981. Barbara is the elder of the two and was named after her paternal grandmother (and former US First Lady, Barbara Pierce Bush), while Jenna was named after her maternal grandmother, Jenna Hawkins Welch. Jenna Bush graduated from the University of Texas in Austin in 2004, married Henry Chase Hager in 2008, and has two daughters. Barbara graduated from Yale University in 2004 and remains unmarried.
