A Double Christening at St Alban's

The photo below shows a double christening at St Alban's church. From the dress, it appears to be about 1960.
The vicar is Rev Hewson.
It is not totally sure who the ladies are but the best suggestion so far is Joy Forrester (nee Brumpton) on the left.
The lady on the right might well be Eva (surname unknown but also nee Brumpton), so Joy and Eva were sisters.
The man in the rear in the dark suit may well be Charlie Brumpton, the father of the girls.
Joy was married to Cyril Forrester, they lived in the house near the footpath on the bend in East Lambwath Road.
Cyril was a conductor for East Yorkshire buses.
A double christening like this must be a rare event, so we may well be able to find out more.
