Sibyl Marshal, Countess of Derby

First Name Sybil , Sibyl or Sibilla

Last Name de Ferrers or Marshall

Birth Date 1191, 1193, 1195, 1201, 1204 or 1209

Death Date 1238 or 1254 or 4/27/1245

All five of William and Isabel Marshal’s sons (Sibyl's brothers) died without any children, and the division of all the lands these two individuals inherited, acquired, and held would eventually be split among the children of their five daughters. There is no direct male lineal descent from William Marshal’s line. Of his five sons, three died in unexplained and/or undiscovered manner, Richard was murdered, and Gilbert died in a tournament. There are many unanswered questions about William Marshal’s sons.

The five daughters of Marshal were all married, some more than once, and all had children. The daughters will be presented in regard to whom they married and the names of the children they had by each marriage.

Sibyl (or Sybil or Sibilla)

(b c1201-d 1245) married, before 1219, William de Ferrers, 5th Earl of Derby, and they had seven daughters.

These daughters were:

Agnes (d1290) who married William de Vesci of Alnwick; Isabel (d1260) who married Gilbert Basset of Wycombe; Maud (d 1299) who married Simon de Kyme of Sotby;

Sybil (d 1173/4) who married Franco de Bohun of Midhurst; Joan (d1268) who married John de Mohun of Dunster; Agatha (d1306) who married Hugh de Mortimer of Chelmarsh; and

Eleanor (d1274) who married William de Vaux. Sibilla died after 1238 and William de Ferrers died in 1254.
