She gave them to her twin daughters, who in turn passed them on to their nieces, Gilles and her sister.
"I got the blue one, my favourite colour," said Gilles, 38. "But none of us ever played with the dolls. We knew the story.
"Our family tried to find out what happened to the two girls, but they never came back. We were unable to trace any relatives."
Gilles, a mother of three, decided not to give her doll to her 4-year-old daughter.
"It felt wrong to hold on to them and my sister felt the same way. We wanted to give them to a museum or a place of memory.
"It wasn't easy to give them up but it was the best thing we could do for the memory of those little girls," she said.
The Lévy family were among the last Jews to be deported from France only months before the Liberation of Paris after remaining in hiding in Gemeaux, near Dijon, for most of the war.
The Shoah Memorial yesterday put on display about 200 of the 18,000 objects the museum has collected in the past three years.
Among them was a violin played by a prisoner at Auschwitz, kept by his grand-niece in Angers, western France.
