Top 10 most richest families in the world – Their generations to come can never be broke (With Pics)

4. Christy Walton and family – $28.2 billion

Christy Walton is the surviving wife of John Walton, one of the sons of Sam Walton, the co-founder of the massive Wal-Mart chain. After Sam died, his children took over with shares in the company. John, however, died in 2005 in an airplane crash, leaving behind Christy and one child. Christy and her family inherited John’s wealth, including dividends from Wal-Mart that amounted to $430 million in 2012 alone. A side investment in First Solar also pushed her net worth more than the other Walton siblings.
