After two months, the children â five boys and two girls â were divided among families in the neighborhood.
The eldest brother, then 13, went to work for a baker; a second brother went to work for a shoemaker and later became a priest, spending decades in Madagascar; two became stone masons; and a fifth worked as a restaurant chef. All five sons have died.
Ms. Udry-Dumoulin lived with her aunt, and when she married she moved to another village about 40 minutes away. The siblings were never close, she said. âThey were busy with their own lives,â she said.
Each Aug. 15, to mark the disappearance, some of the siblings would climb the glacier to pray, she recalled. âFor us, our parents were always beside us when we were up there,â she said.
Ms. Udry-Dumoulin, who has had a heart attack and a stroke, said she was no longer able to climb all the way up the glacier.
But now, she said with a laugh, her parents have descended from the glacier, via a police helicopter. âIâm impatient to see them even if they are mummified and black after the 75 years they slept together in the glacier,â she said.
In a phone interview, StÃ©phane Vouardoux, a spokesman for the police in the Canton of Valais, where the couple disappeared in 1942, said that DNA testing was underway on the bodies and on objects found near them.
âWe still do not know for sure if these are the Dumoulins, and we have doubts, though the circumstantial evidence suggests that could be the case,â he said, noting that 280 people from the area had disappeared since 1926 without a trace after vanishing in mountains, lakes or glaciers.
The discovery of the bodies was a matter of chance. Mr. Vouardoux said that a worker for Glacier 3000, which runs cable cars and ski lifts, was walking in the picturesque mountainous area off the trail, near a ski lift about 8,600 feet above a ski resort, Les Diablerets, when he spotted two black rocks he had not noticed before.
When the worker got closer, he suddenly saw the bodies, Mr. Vouardoux said. After several forensic police specialists were dispatched to the scene, he said, they broke through the ice and discovered a book, a backpack and a watch.
Bernhard Tschannen, the chief executive of Glacier 3000, said the discovery appeared to have been made possible by the effects of global warming, which he said was causing the glacier to lose up to half a meter, or 1.6 feet, a year. âThey were lying together, half in the glacier and half exposed,â he said, adding, âWe believe they were walking between Valais and Bern and fell in a crevasse.â
Mr. Vouardoux said that the Dumoulins â a shoemaker and a teacher â had apparently vanished while traveling to a chalet in Bern, although family lore has it that they had gone to milk cows. Their disappearance troubled their hometown, the village of SaviÃ¨se, for three-quarters of a century.
âSomething happened to them,â Mr. Vouardoux said. âWe donât know what that is. This mystery has haunted the village, and this may finally bring a much-needed sense of closure for the village and the family.â
The theory, he said, is that the couple fell into a crevasse.
Search parties combed the area for two months, to no avail. âWe spent our whole lives looking for them, without stopping,â Ms. Udry-Dumoulin told a Swiss newspaper. âWe thought that we could give them the funeral they deserved one day.â
Local legend has it that the glacier at Les Diablerets is inhabited by devils and that has spooked local residents for years. But Mr. Vouardoux said that residents of SaviÃ¨se, a village of 7,000 people, were known more for their appreciation of wine, their fondness for theater and their tenacity.
Mr. Vouardoux said that he was determined to solve the mystery for the sake of the two surviving children, noting that the village credo was: âWe never give up.â
Ms. Udry-Dumoulin, an observant Catholic, said of the familyâs plans: âWe will arrange a funeral for them as if they had just passed away. The religious aspect is very important for me.â She said she hoped to bury her parents in the cemetery where her five brothers are interred.
The coupleâs youngest child â Ms. Udry-Dumoulinâs younger sister, Monique â was also relieved at the news, she said.
The police said that bodies continued to be discovered as glaciers recede. Last year, the body of a German skier who disappeared in 1964 was found in the area.
In 2015, the remains of two Japanese climbers who disappeared during a snowstorm in 1970 were discovered in the Valais area, near the Matterhorn glacier.
And in 2012, three brothers who had been missing since 1926 were found by British climbers on the Aletsch glacier.
