Have a look at the GENUKI Herefordshire site for Towns and Parishes. Ocle Pychard is the normal spelling for this little village, rather than Pitchard. Roughly between Hereford and Bromyard. The mysterious L place is almost certainly Llanwarne, in my view - a small village between Hereford and Ross and where, as it happens, I grew up. Clodock is right next to Longtown, the Herefordshire side of the Black Mountains. You should find Longtown on a site like Multimap. Llangattock in Breconshire is on the Brecon and Monmouth canal route - not difficult to find, 10 or ll miles south-east of Brecon. All of these places can be found on the appropriate county page of www.genuki.org.uk Liz
