Callista Gingrich
In 2002, Newt Gingrich, although not a Catholic at the time, asked the Roman Catholic Archdiocese of Atlanta to officially annul his 19-year marriage to Marianne, on the basis that she had been previously married. Callista, a lifelong Catholic, was instrumental in her husband's conversion to Catholicism in 2009. The Gingriches live in McLean, Virginia.
