Thanks, Mark.
I too, have a couple of paperbacks (?Sutton Libraries or somesuch) of St Helier and district.
I'd be very interested to know if the Piles directory showed the household into which I was born.
Our part of Garendon Road was JUST inside Carshalton's border and its parish. I was born June 1932 and. although I was only 7 or 8 when I moved round the corner (1939-1940) onto the Sutton Bypass, I still remember families like: Applegarth, Symonds, Favell, Nelson, Charrington, Sparks, Stackhouse, Bullard, Clarke, Glass, Gunn, Parker, Chase, Broad, MALLION (that's US!), Morton, Dobwell, Winskell,...to name but a few! I believe my parents and older brothers moved-in (from Islington) circa 1930.
Do let me know if there's anything at all I might be able to fill-in for you.
Cheers,
