Whenever I look at an English problem I usually think of marriage indexes. Most counties have their marriages indexed at least 1800-1837 and some 1538-1837. To make certain, I went to the Family History Library in Salt Lake and checked on the CD databases availalbe. There is a great collection that is easy to use. For a brief review:

Berkshire has a probate index and many Christenings, marriage and burial indexes (CMB)

Cambridge has Christenings, marriages and burials, poor law index and many other records.

Cheshire marriage indexes 1754-1837 and many misc. records

Derbyshire has many miscellaneous CDs. Their marriages are 100% indexed on line (http://www.derbysmarriages1538-1837.co.uk/)
