Looking for old penfriend

My mother, Doreen Thompson, used to write to a Joseph Borg as a penfriend round about 1940. She would have been 14 and she used to live in Redcar, England. Mr Borg, who would have been of a similar age, lived in Sliema. He had two sisters, one called Gladys and the other who had married an Englishman and went to live in London.

My husband and I are on a holiday in Malta until June 10 and we would like to meet Mr Borg or relatives of his. We can be contacted at the Preluna Hotel, Sliema (Room 7415). Our UK address is 7, Stoupe Grove, Redcar, TS10 2QN, England.
