I have found this marriage in 1919
GRIFFITHS John GRIFFITHS Mary A Dudley Register Office Dudley Register Office DRO/042/179
Now, I know that we have a John (Jack) Griffiths who married his cousin Cissie Griffiths around 1918. The above is the only Griffiths/Griffiths marriage record I can find around that time, but the girl is Mary A, not Cissie.
I'm wondering if Cissie is a nickname/family name and not her given name.

Posting a lookup for this too.
