This is my grandfather, John P Lockton, and he was based at Raniket in North India. My grandmother died in 1925 while giving birth to my twin uncles; both survived! My mothers was only 5 years old at the time and she and her siblings were placed in a catholic boarding school.
I am planning to try and find my grandmother's gravestone, which I have a photo of, but first I need to identify my grandfather's regiment to try and find the military grave where she may be buried. Any help would be gratefully received.
