I went into the Portsmouth Library today and although they hold very little on St Stephen's here's what I found.
It was bombed on the evening of 10 January 1941 in the first major raid by the Luftwaffe on Portsmouth. 300 raiders took part that night and some 25,000 incendiaries plus hundreds of high explosive bombs were dropped. In all 6 churches were destroyed. At that time St Stephens had a local population of around 13,000.
Apart from some interior paper prints of St Stephen's interior there was just one print in a local book of the architect's impression of a frontal view, very much like the photo from Wendy.
(I must have had a senior moment when I said previously the view of the church advised by Wendy was from St Stephen's Rd, it was the frontal view from Kingston Rd which is a highway. St Stephen's Road runs to the rear of the church.)
The congregation moved to its Mission Hall about 1/4 mile away after the bombing and there it remained until 1961 when the last baptism and wedding took place. In spite of the loyal congregation's pleadings for the church to be rebuilt they were defeated and the church was demolished and the site, as far as I can measure it, became a new Fine Fare supermarket. Bit of a sad ending really but not unlike that of the other bombed churches.
His house at 34, Chichester Road North End Portsmouth is now a doctor's surgery so that turned out better.
Also about the 'daughter?' Dorothy Hilda Debenham. The girls' school at 10 Merton Road, Southsea is still there and was the right hand half of the nursing home in this photo link:

Debenham, Gerald Dalton , MA Cambridge
