Ellul, Camilleri, Grima, Sammut info

I need to find info on John Ellul(b ?, d. 1975), who married Caterina Camilleri (b. ?, d. 1946) and had my grandfather Joseph Ellul (b. 1916, Hamrun), along with siblings Maria, Rita, Rose and Vitorine. Joseph married my grandmother Rose Grima (b. 1918, Hamrun), daughter of Emanuel Grima and Carmela Sammut. They are said to be from Floriana originally. I have not substantiated this. Rose's siblings include Pawla "Polly" and Joseph (who later moved to the U.K.). My grandparents emigrated to Toronto, Ontario, Canada in 1952 with their young children. Any information on any of these persons and ancestors and descendants alike will be greatly appreciated to say the least.
