William Clayton writes in his journal: "M[argaret] and A[aron] had a long conversation together. She. has stood true to her covenant with W[illiam] C[layton]. I also had some talk with him and although the shock is severe he endures it patiently. And I pray the Great Eloheem to make up the loss to him an hundred fold and enable him to rejoice in all things. My heart aches with grief on his and M[argaret]'s account and could almost say O that I had never known h[er]." Aaron Farr had just returned from a mission to find his fiance', Margaret Moon, pregnant and secretly married to Clayton as a plural wife.
