Dorchester, Dorset, St Peter

[Bill Hibbert]

I have a question, not really bell history, that I hoped the experts 
could help me with.

The dedication of Dorchester, Dorset (the eight) is listed in online 
Dove and CD's book as St. Peter. Printed Dove has it as Holy 
Trinity, St Peter and All Saints. Holy Trinity church in Dorchester, 
once an Anglican church, became an RC church in the 1970's. Can 
anyone confirm the actual dedication of the church with the eight?

Thanks,

Bill H
