FamilySearch
Although you won’t get images of the registers, as you do on Findmypast, the Cheshire collection on FamilySearch is just as extensive and free to access. There are also parish registers from Lancashire Record Office and the Diocese of Manchester, mainly from the historic county of Lancashire but with a few parishes from Cheshire and Yorkshire. There is also an excellent collection for the Isle of Man, in association with Manx National Heritage, including images.
