Evidence
from the inquisition post mortem of the wife of William’s brother Robert (CIPM v.1 no. 122):
Amy, late the wife of Robert son of Aeri.
Writ super caus â captionis to the sheriff of Salop, 13 Jan. 32 Hen. III. Inq. (undated.)
Salop.
Withiford mill was bequeathed to the abbey of Hageman alias Haghman by the said Robert, and after his decease William his brother entered upon his lands as heir, and dowered the said Amy of the town and mill of Withiford; and the abbot impleaded the said William, who gave him 20s. yearly for the mill to be received at Wetenaston and Muchelegam? Amy died seised of the said township and mill in dower, and the abbot was never enfeoffed thereof.
The sheriff took the mill with the town into the king's hands because there was no escheator, and the other lands of the heir of Withiford were in the king's hands.
