Three siblings dead by 41: The complicated story of the Carter family.

The loss of Bobbie adds another complicated layer for the Carter family, who have faced many challenges over the years.

Who are Nick and Aaron Carter?

Arguably the most well-known of the five siblings, Nick and Aaron were born seven years apart and were raised by their parents, Jane Elizabeth and Robert Carter. They had three sisters – Bobbie Jean, Leslie and Angel.

Their childhood was relatively quiet, but Nick’s rise to fame with the Backstreet Boys in the early ’90s put the family in the limelight. And this meant it also thrust a young Aaron into the spotlight.

By 1997, Aaron performed as the opening act for the Backstreet Boys, per Nick’s recommendation. At the time of that performance, Aaron was only nine.

“Nick’s the one who always wanted me to do this job that I’m doing right now,” an 11-year-old Aaron told MTV News in 1998. “He just looks out for me a lot.”

Soon after that performance, Aaron became the quintessential teen pin-up, with bubblegum songs like ‘I Want Candy’ flinging him into mainstream fame. His second album, Aaron’s Party (Come Get It), sold three million copies in the United States. At not even 16 years old, Aaron had released four albums.

“My mum and dad did a really good job,” Aaron told PEOPLE of his childhood stardom. “When I grew up, I had a bodyguard outside my door. I wasn’t allowed to party. I wasn’t allowed to do anything. As soon as I got, like, 17 years old, 16 years old, I started being very rebellious.”
