Constance’s aunt who lives a two-hour drive from the Hardcastles. Mrs. Hardcastle intends to send Constance to Aunt Pedigree when she learns that Constance hopes to elope with Hastings, but Tony drives Constance and Mrs. Hardcastle in circles and they never arrive, so Aunt Pedigree never appears onstage. Aunt Pedigree’s name is suggestive of her role: she is meant to protect the family pedigree from marriages that do not get family approval.
