Petronella Longespee, nun at Bradenstoke?

FMG: FMG: England, Earls Created 1138-1143:—
"PETRONILLA Longespee (-buried Bradenstoke Priory). The Book of Lacock names “Petronillam” second in a list of the daughters of “Guillelmo Longespe”, adding that she died “in virginitate” and was buried “apud Bradenestok”.[1799]" — Annals of Lacock Abbey, Appendix I, Book of Lacock, p. iii.
Note: That isn't much to go on, but it does suggest that she took the veil.
