The series also includes a set of copies of family letters (including some written by Nevil Maskelyne), and notes by Theresa Story-Maskelyne on the letters of Lady Clive.
The letters are primarily from Nevil Maskelyne but include three sent to Andrews by Margaret Maskelyne, following the death of her father.
