Angelina Jolie and her brother JAMES HAVEN will mark the first anniversary of their mother's death by making a sizeable donation to the Los Angeles hospital where she lost her battle with ovarian cancer. Marcheline Bertrand passed away at the Cedars-Sinai Medical Center on 27 January (07) aged 56. And Jolie and Haven plan to pay their respects to their beloved mother with a day-long vigil on Sunday (27Jan08) to commemorate her life. The event will see Jolie take her four children - Maddox, six; Pax, four; Zahara, three, and biological daughter Shiloh, 19 months - to the L.A. hospital with her brother to hand over the money to the hospital's women's cancer research fund. But Haven is said to be concerned about how the Tomb Raider star will cope with the emotional day. A close family friend says, "James and Angelina adored their mother. They want this day to be solely dedicated to her memory. "(But) Angie still weeps for her a lot and James has been saying how he's worried she will fall apart on Sunday." Both siblings were close to Bertrand, but Jolie in particular struggled to come to terms with her mum's death and recently praised her boyfriend Brad Pitt for helping her through the trying time.
