Hi Catherine,
All of the German marriage records that I have been able to locate in Germany (Celle Region) to date show the Bride and Groom's parents as well as where the bride and groom are from. Do you know the specific District, etc where this union was registered? I'm not currently subscribed to Archion, but you can see what records have been digitized and are available online for the various regions without charge from their site. I will likely be subscribing to it again in the near future once my research progresses. If you have more information, then a search would be possible.
