Hi Philly and welcome to Rootschat.
As you probably already realise, this marriage took plce before the introduction of civil registrations so you will need to consult the parish records for Aston, probably SS Peter & Paul, the parish church. These are held in the archive department at Birmingham Cntral Library, which can be contacted as follows:
Birmingham Archives and Heritage, Central Library, Chamberlain Square, Birmingham B3 3HQ. Tel: 0121 303 4549. Email:
archives.heritage@birmingham.gov.uk ...
I'm sorry I can't offer to look this up fpr you, as for the moment I am unable to get to the library.
Good luck with your search.
Keith
