There are two Ridge Hills on the 1:50,000 Ordnance Survey maps covering Herefordshire. The one David Meredith spotted is in square 5035. The other is midway between Much Marcle and Sollers Hope at square 6233. There is no Nestor Brook on the OS, but there is a Norton Brook Farm also in square 5035.
