Jeff Bezos's mother Jacklyn Gise was just 17 years old when she had her son in 1964. His biological father, Ted Jorgenson, was 19, but didn't know he had a son right away because Gise decided to raise the baby on her own. By the time Bezos was four years old, his mother married Cuban immigrant Mike Bezos, who ultimately adopted Jeff. Mike, an engineer who eventually found success in the U.S. despite coming to the country as a teenager with nothing, was able to help his son launch Amazon with a $300,000 loan in the early 1990s.

In 2013, he joined the Member Board of Directors for iMentor, a non-profit organization that matches high school students with college education mentors.

Christina Bezos-Poore is more of a mystery than her brothers

Christina Bezos was reported to have been born in 1969, though publicly available information about her early life is contradictory. While residing in Tex., she met and married Stephen S. Poore in 1995. Now Christina Bezos-Poore, she maintains a private life.

However, she did speak up when her brothers Mark and Jeff soared into space on the reusable rocket New Shephard from Blue Origin. According to CNN anchor Ana Cabrera, "She told her brothers to hurry back and that she loved them."
