Overview
Agatha had at first been affianced to Percy Craye, though upon reading in the papers of his behavior at a Covent Garden ball, she had ended the engagement. She then married Spenser Gregson, who is her husband for most of the Wodehouse canon, though he dies in time for her to marry Craye, who had by then become Lord Worplesdon, Earl of Worplesdon, whereupon she becomes Lady Worplesdon. She has one son, Thomas Gregson, (Thos.). She is also the stepmother of Lord Worplesdon's daughter, Florence Craye.
She has a pet dog companion named McIntosh. It is a West Highland white terrier and was the center of the plot of Episode of the Dog McIntosh and its TV adaptation Tuppy and the Terrier, in which Bertie almost lost it to a Broadway producer.
Aunt Agatha has been described as "the best image of the dialoguing philosopher".
