They had a son in 1937, but the baby died after just six months and the following year Morano kicked out her abusive husband.
The mayor of Verbania, the city in northern Italy in which Morano lived, said the community would always remember her.
Emma Morano, an Italian woman believed to have been the oldest person alive and the last survivor of the 19th century, died on Saturday (April 15) at the age of 117, Italian media reported.
Dr Bava said he had last paid his near-daily call on her on Friday.
She swore to the end that the secret of a long life was a diet of two raw eggs a day. Jamaican Prime Minister Andrew Holness tweeted his congratulations to her. "I think I was one of the first in Italy to do that", she said.
Ms Morano was born on 29 November 1899 in the Piedmont region of Italy.

In 2011, she was honoured with the Order of Merit award by the Italian state and on her latest birthday she received the congratulations of both the current head of state Sergio Mattarella and Pope Francis.
A celebration entitled, The woman who saw three centuries, was held in Verbania in honor of her 117th birthday.
"I didn't want to be dominated by anyone", she told The New York Times. Since then, she supported herself, lived alone, and worked in a jute factory until the age of 65.
But, she told La Stampa newspaper when she was a spritely 112 that she was left with little choice.
Her eyesight did become very poor and she latterly spent much of her days sleeping.
She also defied health advice, Dr Bava said on Saturday. Some doctors had warned her against eating three eggs daily, which she did for years, but she ignored their advice.
