More than 70 years after they entered the White House together, Dwight D. Eisenhower’s and Richard Nixon’s families remain close — so close, in fact, that Nixon’s daughter is married to Eisenhower’s grandson. Julie Nixon and David Eisenhower were married in 1968 and have three children together: Jennie (born 1978), Alexander (1980), and Melanie (1984). The couple met as children at the 1956 Republican National Convention, which renominated the elder Eisenhower and Nixon as president and vice president, respectively, and began dating a decade later when they attended separate colleges in Amherst, Massachusetts. Julie and David were wed on December 22, 1968 — after President Nixon was elected but before he took office.

Eisenhower selected Nixon as his running mate in 1952, and the two cruised to victory in that year’s election by winning 442 electoral votes; they did even better four years later with 457. (People really did like Ike.) Adlai Stevenson II was the Democratic nominee in both elections. And though Nixon’s presidency isn’t remembered fondly, what with him resigning in disgrace, he was an Electoral College juggernaut in his own right. Nixon won a respectable 301 electoral votes in 1968 and 520 in 1972, carrying every state but Massachusetts and Washington, D.C.
