I am SO SO SO SO SORRY, Welsh Cockney
Where on earth did I get John from? very senior moment there.
so - the right marriage is :
AP/MAy/Jun 1888
Atcham 6a 1225
JOSEPH Probert
and yes, there is an Ann Preece on the same page!
Getting the cert will give their fathers.
But I am not suree xactly what you are wanting or what you already have. You said you have nothing at first - but now you have his parents, date and place of birth, number of siblings, name of one sibling, exact dat of marriage (implying you have marriage cert, or someone has)...
Have you looked for him on 1881 census for example?
