Well I never!!! I didn't even know this existed!! I can see the typed up very useful information but when I tried to open up an actual scan nothing happened with either link even though I did different formats. Should I be seeing a copy of a parish register or an actual marriage certificate or am I missing the point here?
Silvery is correct there is nothing else that you can see other than what has been put on the postem. The scan is what you should be checking against before ordering a certificate or if you think there is a transcription error as it is a copy of the GRO index. You can also report transcription errors on this site.
The example I gave you also shows on the entry for her husband James Frederick Wilkinson You can if you like leave an email address if you are hoping someone may contact you, personally I don't.
You can leave your e-mail address if the postem concerns someone who is on your tree, however you can replace with words like "at" and "dot" to prevent it being harvested by hackers. By putting my e-mail in this form a while back I was contacted by another researcher of the same family tree so this does and can work. Have just downloaded to "WRONG" death certificates from the GRO so have posted details on the relative postem FreeBMD record. didn't take long, including details such as where and when died, home address and informants name address especially if a relative. This when seen would enable a search for a burial, newspaper notice and electoral rolls which are now coming online.
