The Hollywood actress and her relatives were left reeling following the death of her father, Dr. Antony Kidman, last year (14), and now Angus Hawley, who had four children with Kidman's sister Antonia, has passed away.

Hawley, 46, who split from Antonia in 2007, is believed to have suffered a heart attack in New York City while in town to attend a business conference.

The tragedy leaves Kidman's nieces and nephews, Lucia, 16, Hamish, 14, James, 12, and Sybella, eight, without a father. Hawley is also survived by his second wife, Prue Fisher, who he married in 2011.
