It is confusing, isn't it?

But fascinating!
Plenty of questions, if that's okay!!
1. Are you absolutely sure that the Ethel G of the 3 marriages is the same person?
2. Have you found deaths for husbands 1 & 2?
It's obviously significant that your Herbert
Scott Young has been given the middle name 'Scott' - making you think that his father was Scott Kurr Young. However, it seems that, by the time of Herberts's birth in 1923, Ethel was married to Robert Usher! (perhaps a 'homage' to her deceased first husband - possibly also a friend of husband no. 2?)
3. Was Scott Kurr Young any relation to Robert William Young? Do you have Robert W's birth certificate? Scutt Kurr is a rather unusual name for GB. It sounds American to me - were the US in the war by then?
4. Does Herbert's birth certificate give his mother's name as Ethel G. Young (nee Harris) or just Ethel G. Harris?
5. Don't you think it's interesting that Ethel G's 3rd husband was called
Robert W Usher? Is there any chance that your Robert William and this Robert W Usher could be one and the same (i.e the person she was married to when she gave birth to Herbert)? Why would he change his name? Could the registrar have made a mistake and written the wrong name on the marriage certificate? (it happens!)
Incidentally, where did all this take place?
I'll shut up now...
