Thanks Little Nell. I have since contacted the Dorset Heritage Centre in the vain hope that they might have the Bishops Transcripts for 1881 but they have them only to 1846, so no help there.
The archivist I spoke to made the same suggestion as you, but as I understand it Wynford Eagle was a Chapelry of Toller Fratrum & both are now closed churches,
I have not yet found any Church ministry or redundant church organisation that has responsibility for the two churches so am at a loss where to look next. So any suggestions would be heartily welcome.
However on the Dorset OPC for these parishes both have lists of monumental inscriptions with dates of death up to the 1950s. Therefore the conclusion must be that there was a burial register post 1880 but where that register is now remains unsolved at present.
As I live in South Devon a visit to Dorset is impractical until I have a lead.
