Pity the GRO copy of the M cert gave no fathers names or father's occupations, the probability is that both fathers were deceased. Two further options are to see if you can find the fathers name connected to the marriage of a known sibling (even though there will be a substantial time gap) and as suggested, to enlist the help of someone on the Kent side of Rootschat to look up the parish registers of St Mary the Virgin with the date you have to see if those records contain more info. The names of any witnesses for example might assist. Roy G
