In our church, Knighton, Radnorshire, there is a plaque naming all those who were killed in WW1. It is also repeated on the Cenotaph in town. One of the names on there is O. Langslow. I visited the CWGC and there doesn't appear to be anyone of that name on their site. I have also visited Code: http://www.roll-of-honour.com/Radnorshire/Knighton.html they don't know who he is either. What is my next move?
