William McArthur Mayo (Bill) and Eliza Mary (Lila), née Saxelby corresponded frequently with their daughter Daphne. Sometimes both parents would write individual letters to Daphne on the same day, at other times they would each write in the same letter, and they would also write to her individually. There are approximately 1422 items of correspondence in this subseries dating from 1919 to 1959. Bill would often write about financial matters including Daphne's rental property in Brisbane. Occasionally Lilia would get the date wrong and, if discernible, this date has been corrected in pencil on the letter. As Lila's health deteriorated, her handwritten became more difficult to read.
