Yep.
Quiet unassuming guy. Was the second husband of this sister and the step father to her two kids.
I went out with the step daughter for a few months and could never understand why she was nervous around him. I was only about 19 myself and didnt pickup on what was going on. He really liked me and wanted me to marry his step daughter (lucky escape - she was barmy!)
It was several years later that it began to dawn on me what was going on there.
It turned out that the elders knew all about it and regularly "counselled" him. Wife continued to wear dark glasses.
