Question for those in the know...

For old church burials in the church interiors, for whom there isn't anything listed in Felthams and the church interiors have been replaced, are there any ancient records of any monuments that may have existed?

The Caesar family and Bankes family both have later monuments in their respective church interiors, I was wondering if there was any records of earlier ones anywhere, or whether they are lost forever...

Cheers
