The monogram M L points to an Earl or a Countess with a title that begins in L. There were a number of Countesses in 1897 that fitted that description: Mildred Countess of Lichfield; Millicent Countess of Lindsey, whose husband also had the Christian name Montagu; Mary Countess of Longford. Ernestine Mary Countess of Listowel, and Alice Mary Countess of Loudon are also possible.
