'The Macleans frequently visited Melinda Maclean's mother and stepfather in Manhattan and at Dunbar's country place in the Berkshires. '

... (earlier in the wikipedia article below):

'One evening, December 1939 in Paris, Maclean met Melinda Marling. The daughter of a Chicago oil executive, she was a teenager when her parents had divorced, her mother moving to Europe. In October 1929, Melinda and her sisters went to school at Vevey, near Lausanne, where their mother rented a villa, and spent their holidays at Juan-les-Pins in France.^[20] Melinda Marling's mother moved to New York, marrying Charles Dunbar, an executive in the paper industry, and brought her daughters to live with them in Manhattan, where Melinda Marling attended the Spence School. After graduation she spent some months in New York City then returned to Paris, where she enrolled at the Sorbonne in Paris to study French literature.^[21] Melinda Marling was introduced to Maclean, in the Café Flore in December 1939, possibly by Mark Culme-Seymour. Culme-Seymour later described her as "quite pretty and vivacious, but rather reserved. I thought that she was a bit prim. She was always well-groomed, lipstick bright, hair permed, a double row of pearls around her neck. Her interests seemed limited to family, friends, clothes and Hollywood movies."^[22]'
