Moving to Monaco Forums

Can anyone help me please. I am trying to trace my aunt who moved to Monaco probably in the 1960s posibly 1970s. I have some family news I need to pass on to her and have no forwarding address. Her name is (or was - as she may of course have married or changed her name) Jean Brooks she came from London. I have tried searching the Monaco phone book but she is not listed. Can anyone help please. do you know her or know how I could trace her, Many thanks
