Of a Whitton landowning family
Ancestor in Isleworth?
The following (apparently re-used) brass inscription is/was in Isleworth Church:
Of yo charyte pray for the Soule of Willm Chase Esquyre
Sutyme sergeaunt to Kyng Henry the viii & of hys most honourable
Household of hys hall & woodyerd which decessed the viii day
Of maye yn the yer of oure lord god MCCCCC xliiii
Of whose soule & all crystyn sowles ihu have mercy amen
It is/was attached to an effigy of a knight whose armour has been dated to around 1450, about a century earlier and conceivably an ancestor of William.
