Roger FitzPiers FitzOsbert and predeceased her husband, who d. shortly before 6 Mar. 1305/6. Some authorities state that Sarah d. s.p., but others say that she had a da.

On her husband's death Sarah's lands were divided between the descendants of her father's sisters, Margaret, wife of John de Thorpe, and Isabel, who m. John de Valoines; claims were made for the heirs of a 3rd sister, Maud, but were not substantiated. At the beginning of the 14th century Margaret was represented by her grandson John de Thorpe, while Isabel's heirs were her great-granddaughters Rose, wife of Edmund de Pakenham, and Cecily, wife of Robert (de Ufford), Lord Ufford (Close Rolls, 1234-37, p. 43; Cal.
