I am also researching this family and one of my contacts gave the parents of Zachariah as Tabrum Garrod (c.1775)and Mary Granger(c.1781), but I have not been able to confirm this myself. Zachariah was born at Denston about 1810. Perhaps there is a member living in this region who has access to the parish registers who may be able to help Pauline Jones 8317
