There are many Mary HODGES baptized in the area during 1705-1715 none of which would present an obvious candidate for Mary HAWKER's mother.
Applying the names of her children we might guess that her parents were Edward and Ann. One baptism matches this theory: Mary HODGES c. 11 Apr 1708 by Edward and Ann HODGES in Tarrington, Hereford which is 25km from Chaceley.
