Looking for info on Josephine Maria Bassi

From Halina Racki, Britain

Trying to find anyone who knew Josephine Maria Bassi born 1923 or her family – father Cesare Bassi (b.1872 Switzerland) and brothers Cesare Rino Bassi or Vido Bassi born 1919 and 1921. I believe Cesare Bassi (father Adolfo) came to London from Bellinzona and worked as a waiter- they lived in Soho and my mum went to a French catholic school near Leicester Square.
