On their return from the park they found Willoughby's curricle and servant in waiting at the cottage… He then hastily took leave of them all and left the room. They saw him step into his carriage, and in a minute it was out of sight. (15)

Since Willoughby said he was going to send his groom into Somersetshire to fetch Queen Mab to Barton (12) the groom is likely in his employ rather than one belonging to Allenham. Above, Willoughby is leaving for town with at least one servant. As Mrs. Smith has disinherited him it is unlikely she has loaned him a servant. Also Mrs. Jennings tells Elinor, “they say he is all to pieces. No wonder! dashing about with his curricle and hunters!” (30). From this last bit of information I think it is fairly safe to say Willoughby came to Barton with more than one servant to manage his curricle and his hunters. Anyway that is my guess about Willoughby’s servant situation. His groom squealing to Mrs. Jennings’ maid (13) may just have no loyalty to his employer as described in BarbaraB’s post. That Willoughby has not earned the groom’s loyalty is not surprising. (:D)
