One’s birth order could affect success more than you think.

While there are no extensive studies on whether there are more famous older siblings than famous younger or middle siblings, some say older children tend to become more wealthy and successful than their siblings.

“A child’s position in the family impacts his personality, his behavior, his learning and ultimately his earning power,” Michael Grose, author of “Why First Born Rule the World and Last Borns Want to Change It,” told AOL. “Most people have an intuitive knowledge that birth order somehow has an impact on development, but they underestimate how far-reaching and just how significant that impact really is.”

Here’s a list of stars who are the oldest in their family and lend some credence to the idea that a family’s firstborn is typically born to be successful.
