Lisa Marie Presley was the only child of legendary singer Elvis Presley - and it's often been asked whether the King of Rock n Roll wanted more kids.
Exactly nine months to the day after Elvis married Priscilla, Lisa Marie was born on February 1, 1968.
Lisa Marie, who tragically died on Thursday at the age of 54 following a cardiac arrest, was the couple's only child and they separated in February 1972.
Elvis didn't go on to have any more children before his death in August 1977, when Lisa Marie was just nine-years-old.
This meant that on her 25th birthday in 1993, she inherited her late father's Graceland estate, which had grown to be worth an estimated $100 million.
Priscilla has previously spoken about how she and Elvis came up with Lisa Marie's name - and some speculation was not true.
Explaining on Facebook, she said: "I bought a book of baby names for Elvis and I to choose from. We would lay in bed night after night looking through all the names that would sound good together. We decided that Lisa Marie was beautiful for a girl…She wasn't named after anyone."
She also dispelled a rumour over the naming of her daughter, adding: "From what I hear, it was written somewhere that we may have taken the name Marie after Col. Parker, his manager's wife, who was named Marie.
"That is not true. We just simply... liked those two names together."
Elvis and Priscilla had also decided on a boy's name which also had two parts.
Priscilla revealed: "I loved the name John Baron for a boy...he agreed."
There has been a lot of speculation as to whether The King wanted any more children.
One person who was able to give some insight was Danny Smith, the son of Elvis' cousin Billy, who grew up at Graceland.
Speaking on the Memphis Mafia YouTube channel, he said: "It's been said by different people, yay and nay. And like I said, no one person was around Elvis all the time.
"I don't know what he may have told other folks and he never told me that he did. But I just had that feeling or felt like he was very content and happy with Lisa and just the way things were going.
"I personally don't think he was looking to have more children. Only really Elvis would know that but, my view of it…that's what I personally think."
Lisa Marie tragically died on Thursday at the age of 54 following a cardiac arrest.
Paramedics rushed to her house in Calabasas and transported her to hospital after being able to regain a pulse. Sadly she died while receiving treatment.
In a statement, her mum Priscilla said: "It is with a heavy heart that I must share the devastating news that my beautiful daughter Lisa Marie has left us.
"She was the most passionate strong and loving woman I have ever known. We ask for privacy as we try to deal with this profound loss. Thank you for the love and prayers. At this time there will be no further comment."
Tributes have flooded in from many people, including ex-husband Nicolas Cage and Grammy award winner Diane Warren.
