During a social event at the mansion of then-Minister of Magic of France, Charles Moreau, Apolline met Alain Delacour; an aspiring law student with ties to Wizarding France's Democratic Party, the main opposition to the authoritarian government of magical France. The two began a relationship, marrying in 1976. As a result of the marriage, Apolline had two children; Fleur Isabelle and Gabrielle Dominique Delacour. Apolline's husband was a core part of magical France's Quiet Revolution, which saw the restoration of democracy and the fall of the Auror-led government which ruled unopposed for a decade.
Apolline continued her modeling and lived to see the marriages of her two daughters; Fleur to Italian wizard Pietro Maximoff and Gabrielle to his Romanian step-brother, Mateo Maximoff. Through those two marriages, Apolline gained five grandchildren, all but one of which are Veela.
