The current record for Oldest Couple to Marry was set on Feb. 1, 2002, when "Francois Frenandez (b. 17 April 1906) and Madeleine Francineau (b. 15 July 1907) exchanged marriage vows at the rest home Le Foyer du Romarin at Clapiers, France, at the age of 96 and 94, respectively."
This wedding flew in the face of a suggestion printed in the Boston Gazette of Aug. 13-20, 1733, playfully aimed at preventing unhappy marriages:
When two old Creatures, that can hardly hear one another f--t, but hauk and cough Night and Day, and can propose not the least Comfort to themselves in the Thing, yet will marry together to be moor miserable, let them be deemed non compos, and sent to the Mad-House.
