"The aim of the project is to make available, in a reasonable period of time, all the information in each of the parish registers of the ancient county of Cheshire. This aim covers information in both the original Parish Register (PR) and the Bishop's Transcript (BT), since despite its name the latter is to some extent an independent source. The period of transcription is from the earliest known entry in each PR and BT up to 1871."
I should add that this is a FREE resource.
