Blanche Longford is the overbearing mother of Alistair Longford, grandmother of Teddy Longford and great-grandmother of India and Texas Longford.
Blanche arrived in September 2010 for the wedding of Alistair to Cindy Cunningham. Alistair revealed to Cindy that he had been married three times previously, to which Blanche took a disliking to each wife and successfully ruined the marriage. Blanche's intentions to stop Cindy from marrying Alistair failed, and the pair were married until Alistair's death on their honeymoon in 2011.
In February 2011, Blanche attended the funeral of India, who had been murdered by Silas Blissett at Christmas. Giving her family little support and sympathy, she shouted at India and Jamil Fadel, and called granddaughter-in-law Melody Longford a "walking pharmacy" for taking strong sleeping pills, which left her feeling drowsy. When Texas went missing in search of drugs and Melody went to look for her, Blanche was hellbent on attending India's funeral without them.
