HRI Online Publications is the publishing arm of the Humanities Research Institute at the University of Sheffield. They have some well establshed databases such as the Old Bailey Proceedings on line, but have now just launched the Cause Papers Database, documents dealing with the church courts of the Diocese of York 1300-1858.

The documents detail a wide range of issues including marriage, separation taxation as well as church ones. The database is searchable by surname and you can view images of the original documents, so if you are researching in this area its worth a look.
