As CaroleW guessed, the only additional information in the baptismal register is confirmation that Ann was a Singlewoman and her address: Kemnal, Chislehurst. Kemnal is between Chislehurst and Sidcup. Baptised on the same day was Edmund, son of Adolphus Frederick and Charlotte Amelia Slade of Kemnal Manor (Ancestry has them as Adolphine and Charolotte). I had hoped to find Ann somewhere in or nearby their huge household at HO107; Piece: 1606; Folio: 505; Page: 57, but I can't see her. Maybe at the time of the birth Ann was staying with a relative whose name Cathy will recognise, but that's a long shot.
