The Grey or White Lady is one of Seckford Hall's most oft-cited apparitions. Described as wearing a long, flowing greyish-white gown and sometimes glowing faintly, her identity is shrouded in mystery. Theories link her to Lady Margery Seckford mourning a child, a 17th-century Seckford relative pining for a lost love, or even a pre-Tudor spirit. She is seen in the upper corridors, particularly near the old nursery area, at the top of the spiral staircase, and wandering the gardens by the yew trees at dusk. Witnesses often sense a deep sadness emanating from her. Though sorrowful, she is considered a gentle presence, sometimes thought to watch over brides or children at the Hall.
