Not sure if this helps you but have you checked the records available from the India Office? (http://indiafamily.bl.uk/UI/Home.aspx
I ran a quick search for you and found Dorothy Alice Muriel PRESTON married Charles James Johnson REED on 12 Dec 1933 in St David's Church, Namtu. She was a nurse - he was an engineer.
If you are chasing up family info in Burma/India, the records on the above link can be of some help. They mainly cover the years from the late 1700's to the mid 1900's.
Cheers for now,
