A DEVASTATED Greenock family have spoken of their pain after losing a second child to an undiagnosed heart condition. Neil and Susan Holleran lost their beautiful daughter Megan in April 2007 when she passed away very suddenly at the age of just six-and-a-half. Last June tragedy struck again when Megan s brother Zachary tragically passed away aged 14. Parents Neil and Susan say that the loss of Zachary 13 years after Megan left them - and the teenager s other siblings Bryan, Alisha, Marc, Neil and Lynn - distraught. Neil, 68, said: We re still not over Megan and now we ve lost Zachary. We just have to take things a day at a time.
