With reference to the above link, I need to point out a correction that needs to be made to the names of his parents.
The MI website states that H.W.M. Stewart was the son of George Anson Moncrieff Paul and Dorothy Bowman Gilroy of Carre or Stewart, but in fact G.A.M. Paul was his brother and Dorothy was his wife. H.W.M. Stewart's father was in fact Ernest Paul, 2.9.1864 - 11.4.1942 and his mother was Katherine Coldstream 30.6.1873 - 1.2.1963.
G.A.M. Paul, 31.7.1895 - 15.1.1978, was my grandfather, so Henry William Moncrieff Paul Stewart was my great-uncle.
