I've managed to find a little more info:

"Houndscroft apparently derived its name from the holding of one John Hund while the neighbouring one, now occupied by Moor Court and the Bear Inn in particular, was at that time and for many years, the holding of the Horestone family, possibly named from the very stone which marks the limit of the Rodborough and Amberley civil Parishes."

So, it lies on the boundary of the parishes of Rodborough and Amberley.
