I have also been researching my grandfather and have found records of campaign medals and award rolls for members of P battery. It is all so difficult to find any information about those serving in the Boer War and my relatives never passed anything down. There is a story though that my grandfather was posted as missing/dead but suddenly turning up giving everyone a near heart attack. He also went to India after that of which I know nothing, and ended up a Chelsea Pensioner for a short while before he died in 1950.
It would be very interesting to find anyone who possibly knew him so if you would like to share some information I would like to hear from you.
