Marta Sgubin has spent most of her life caring for three generations of the Kennedy family, including Jackie Kennedy, her daughter Caroline, and granddaughter Tatiana, since arriving in America 45 years ago.
Italian-born Ms Sgubin was in her thirties when she joined the family to be the governess for the then 11-year-old Caroline and eight-year-old John Jr., children of the late President John F. Kennedy.
'John was a little rascal!' she revealed to ABC in a recent interview, referring to Jackie's late son, who died in a plane crash at age 38. 'He was always ready to do something to you, that you didn't expect. It was mischief.'
Ms Sgubin quickly became Jackie's close friend, and when the children grew too old for a nanny, she became the family's cook before taking care of Caroline's own children, Rose, Tatiana, and Jack Schlossberg, who are now in their twenties.
Nicknames for the grandchildren include Moma or Lola for Rose, Momo or Lolo for Jack and Lolita, Momina or 'The Golden Child,' for Tatiana; and for Jackie, it was Madam.
'Jackie had this personality, very classic, you could put a bag on her head and it was still good,' she said.
'I call her Madam because in French it's Madame and in English I took the 'e' out and it's Madam. One day she says to me, "Do you know what a madam is?"
'I said, "no what is it?" She said, "You don't want to know, but call me Madam, it's too cute".'
Tatiana, who calls Ms Sgubin 'a saint,' described her nanny as 'selfless, kind, regimented, and loyal.'
Recalling fond memories of Tatiana's late uncle, she explained how John once let loose seven black water snakes from the Everglades in the house to spook his sister and nanny.
'They were going from toilet to toilet in the house,' Ms Sgubin recounted. 'When I picked him up from school, he was just laughing hysterically.'
She said she loves the family like her own, recalling the deaths of John Jr. and Jackie with tremendous sadness.
'It affected me as much as it affected them. I work for them, but I love them. I love all of them,' she said.
'They were all very dear to me. To lose them was always a big loss. And that you have to deal with by yourself.
'It's not to be together everyday that brings you close. It's the way that you feel about someone that makes you close, and the hard times you go through that make you close,' she said.
She recalled when time when she was homesick for her dog Pucci in France. Jackie gave her a portrait of a long-haired Dachsund and told her that they would have him sent across the Atlantic if she wanted him.
When she wrote a cookbook in 1998 called Cooking for Madam about the recipes she cooked for Jackie, one year before his death John Jr. wrote the foreword, in which he described his nanny as 'part of our family.'
It was after a long overnight flight across the Atlantic that Ms Sgubin, an immigrant from a 400-person village in northern Italy, arrived very late on the evening of September 7th, 1969 in Newport, Rhode Island for her first day of work with the Kennedy's.
She had previously been the governess to children of a French diplomat family in Paris, before taking charge of the Kennedy children, six years after their father's assassination.
On her very first night, she said she made a bold decision regarding the family's dogs had for years, been sleeping in the shed.
She recalls saying to Jackie's mother, Janet Lee Bouvier Auchincloss: 'No, those are our dogs, they'll sleep with me from now on.'
Her assertion was well-received by family, and almost 45 years later, Ms Sgubin is still with the Kennedys.
'I've never been intimidated,' she said. 'But I was happy that they chose me.'
