Thanks very much :) I have some new information which might be of some use.
Ok, Grace Strong was born 7th February 1894, Nottingham
Her Husband William Walden was born 11th May 1891, Hampshire
Their son Kenneth was born 6th November 1914, in Malta.
all three of them travelled from Malta to England (I think they landed in or near Bristol) sometime between 1915 and 1920.
