As the untimely but not so unexpected death of Steve Jobs sinks in, many wonder who will inherit the Apple leader's estimated $8.3 billion fortune.

Steve Jobs was generally considered a good family man as well as technological genius. There was no hint of scandal, but he did have a complicated personal and family life.

Jobs was the adopted son of Clara and Paul Jobs, who are both dead. They adopted another child, Patti Jobs, whom Jobs knew as his sister.

Steve Jobs' biological parents are Joanne Schieble (later Simpson) and Abdulfattah Jandali. Jobs eventually had a relationship with his birth mother but refused to meet his father.

Steve Jobs met his biological sister, author Mona Simpson, when they were adults but he described their relationship as close.

Jobs fathered a child in 1978 with his first serious girlfriend and high school sweetheart, Chris-Ann Brennan. He first denied paternity of Lisa Brennan-Jobs, falsely claiming to be infertile. But a court-ordered blood test proved otherwise and he acknowledged her as his daughter.

Jobs met his wife Laurene Powell in 1989 when he spoke at Stanford's graduate business school. They had three children: Eve, Erin and Reed.

Who Is The Heir?

The family has not as yet disclosed the terms of Jobs' will, but people are speculating about who will inherit his billions.

Jobs registered 338 U.S. patents and patent applications for various technologies. He also owned a 2007 Mercedes Benz SL55 AMG, which is around $130,000. And his 5,700-square-foot home is a 1930s Tudor-style property with seven bedrooms and four bathrooms is estimated to be worth $2.6 million.

Jobs was noted for his lack of charitable initiatives. It was reported that he declined to sign on to the Giving Pledge initiated by Warren Buffett and Bill Gates to get the wealthiest people to give away at least half of their wealth.

But The New York Times reported that he gave $150 million to the Helen Diller Family Comprehensive Cancer Center at the University of California in San Francisco.
