A population of 4.7 million makes ours a pretty tight community. Yet heiress Gretel Packer has managed to keep her children quietly under wraps, hidden in a 10sq km area of the eastern suburbs and out of the line-of-sight of paparazzi for 14 years. Just months after Confidential gave the nation its first look at Gretel's beautiful eldest child, daughter Francesca, 18, she has been seen out this week with her sons Benjamin, 15, and youngest child William Kerry, seven. The mother and sons were joined by grandmother Ros for lunch at one of the Woolloomooloo Finger Wharf restaurants. While Benjamin, Gretel's son to first husband, British financier Nick Barham, bares a striking likeness to his father who splits his time between London and Sydney, youngest son William bares almost no resemblance to his father, spiritual guru Shane Murray, to whom Gretel was married only briefly and divorced in 2007. William was born two months after the death of Gretel's beloved father Kerry but Packer Snr is said to have died happy in the knowledge his adored daughter had found her place as an attentive mother. Benjamin was only about one when he and big sister "Chessie," then about three, made Sydney their home after their mother divorced her first husband in 1999 and left Britain. Barham has settled into fatherhood again, with new wife, one-time Miss World entrant Karen Carwin.
