Yes,
In those days it was a lifelong affliction which flared and subsided, but was not cured
Treatment was limited.
It was certainly sufficiently bothersome to be consistently grounds for disqualification in the forces.
I certainly understand your hesitation in rushing in to yet another certificate. The photo of Leonard shows a darkish chap, but.....
I think the only line of thinking was that Ern CANNON in Tas during the court case (and Geelong 3rd Dec 1910) EQUALS Ernie KING, EQUALS Ern HOPE.
It was suggested in a previous thread that Adeline had rather moved on from BOW by 1910 and that her mother Ruth had "adopted" him as her husband, while Adeline was with KING, CANNON.
It explains why Ruth was ranting in court "my husband"
Adeline was not at court.
I feel as if I'm writing script for B grade movie!
