Are you on ancestry, if so you can look up Leonard Chambers Collins in my tree. There are two divorce cases to look at which are very interesting but quite sad. There is a bit more about him at the end of the thread regarding Reverend William Bookless.
What a poor girl. A wonderful start to her life then she meets and marries this monster. I was hoping that she did die in 1915, at least she would have had a happier end. To die the same year as her second marriage, not fair. Leonard contracted syphillis, no doubt he gave this to Louisa which may then have been the cause of her demise.
