Have you tried ordering any certificates?
It looks like you already have her marriage information.
You can order birth, marraige and death certificates on this website.https://secure2.gov.mt/certifikati/default.aspx
They post overseas.
If your purpose is family history these certificates do have a lot of information on like occupation, age etc. More then the British ones anyway.
You can order certificates back to 1837 the time of civil registration.
The Maltese government are also microfilming their records and putting them online. They only have a few parishes complete at this time but are working on eventually having all of them done. The website ishttp://archives.maltadiocese.org/default.aspx
It's free to register and free to use. Love it!
Let me know if you need any more help.
I have also heard that someone has transcribed the Adami Collection which is a collection of marriages taken place from the late 1500's to late 1800's although they haven't translated them, but it's good enough. I also have a copy of the Adami Collection on cd at home, but prefer to use the archive website.
All the best
