Yes she probably had a psych problem of some form. I do not believe in good or evil. She did not approve of the marriage of her last daughter, who was expected to look after her in her dotage, to my Father. My family on my Mother's side were all a bit crazy it appears. My grandfather? now there is a subject for another thread but interlinked of course to the whole craziness that resulted.
A totally bent up family by most perceptions.
