wolverhamptonhistory.org.uk/resources/familyhistory/index.html This site gives details of baptisms, marriages and burials within the surrounding areas of Wolverhampton.
Please note if you do use the indexes on that site not all of the records from the time frame given are recorded. double check on their home page as each parish has a different start and end date, I have been caught out several times by that fact. Admins sorry if this is not allowed
