A bit late, but:
The Pennington-Bickford home was one of the last houses in Southwick, Sussex going east before Portslade; on the north side of the Old Shoreham Road.. It is now called Harmony House.
Believe that the Reverand's wife, lous, committed suicide, in Portslade, on hearing of her husband's death due to a broken heart at seeing his church - Clement Danes - burnt down in the blitz on London in 1941.
