I am looking for the marriage of my grandfather, Arthur Ernest Guy. I don't know the name of the lady he married (she wasnt my grandmother) but the family story goes that he abandoned a wife and 2 sons in Gloucestershire and lived with my grandmother. He was born in 1891 in London, father Frederick Guy, mother Sarah Ellen (nee Rouse). The marriage I have found was to Priscilla P Trigg, Gloucester 6a 677. Can I find out his father's name without getting the certificate (already have certificates for the wrong Arthur Guy), and can I tell if there were 2 sons without trawling through the birth indexes, especially as i dont know names.
thanks
Diane
