Colonel George Muir Oldham DSO

[smudgepants]

Good evening, I am hoping someone can help. I am looking for the mother's name and cause of death of Colonel George Muid Oldham DSO Royal Engineers, he was born in Largs Ayreshire, Scotland in 1876 and died in Calcutta in India 1955. I have already found his military history and am only really interested in his mother's name, any sibblings apart from his brother  Dr. J. H. Oldham, C.B.E., and as I say the cause of his death. 

Thanks in advance.
