Battersea and Wandsworth

[Daphne]

All of my mother's family were living in and around Battersea by the late 1800s, so I visited the LMA to search the Parish Registers for Battersea and Wandsworth. I discovered that quite a few Registers had not been desposited. In August last year I tried writing to a couple of churches (St Faiths and Church of the Ascension) to ask if it were possible to visit the churches to look at the Registers. A week or so later my husband took a phone call from one of the churches to say that the Registers are held at another location but that my letter would be passed on. Since then I've heard nothing more. Does anybody know where the Registers for Battersea and Wandsworth are held?
