Thank you all for your help! As a result of your replies I contacted someone in the family who might, I thought, have her marriage certificate. Once found, lo and behold although she was always known as Pamela, and that is the name on her passport, when she married she gave her name as Dot (so probably Dorothy) Tate. The mystery deepens still further since she gave her age on marriage in 1936 as 23 which suggests she was born in 1913, yet her passport gives the birth date 9 Jan1916 in New South Wales. The family story is that she was born under canvas somewhere in the outback! Although the father was always known as Henry Tate on the marriage certificate he is listed as Richard Henry Tate. He was deceased by the time of her marriage (1936) and his profession given as Captain Royal Welch Fusiliers. Sorry to have mislead you with the wrong names! Does any of this help?
