I've had another look and it's definitely a 'P'.
This brief list of 'Broomhill' wounded was published on the 1st May 1915. The photo of W.E. Dalby was published the following week, but I cannot find any text to go with it at the moment.
The names so far in these early issues are dominated by the wounded, but we know there are a lot of KIA as well so we will get to those later I suspect.
