A few weeks after returning from Shanghai, Astor became engaged to Eileen's close friend socialite Ellen Tuck "Tucky" French (1915–1974), the elder daughter of Francis Ormond "Frank" French II (1888–1962) and Eleanor Livingston Burrill (1891–1974). They married on June 30, 1934, at Trinity Church in Newport, Rhode Island. Tucky was a granddaughter of Amos Tuck French and a first cousin of Rhode Island Governor William Henry Vanderbilt III (1901–1981), and had been attracted to Jakey while he was engaged to Eileen. Along with Eileen's sister Phyllis, Tucky was to be a bridesmaid at Jakey and Eileen's wedding. The couple had one son before divorcing in May 1943.
