Tricia Nixon Cox Now June 1971, Tricia was married at the White House. The President walked her down the aisle to tie the knot with Edward Finch Cox, who was finishing up law school at Harvard. They both receded from view shortly after, moving to Manhattan. Edward is a corporate attorney there, and Tricia, now 66, serves on the boards of a handful of medical-research centers. She was also a dedicated mom, staying home to raise son Christopher.
