His granddaughter, Emma, was present in the 1901 census but her parents were apparently not. Since her surname is Ottaway she should not be the daughter of either Alice or Mary who are listed as daughters and have the surname Ottaway and thus assumed to be single. Since there is no source at present for either parent a profile cannot be created yet for Emma.
