Le Fanu

I know next to nothing about Fanu. I feel that I may have read an illustrated version of one of his stories when I was a child.(That might be my imagination) Reading the brief biographical notes just now I was struck by the image of him writing at night by candle light. Surely one of the odder writing regimes. It said in the biographical details that he became a recluse after his wife's death. But the oldest of his four children could have been no more than fourteen. Does anyone know what became of them?

I don't know anything about Le Fanu either; I just like reading his stories!
I think he was a doctor when he was young because he seems to know a lot about the physiology of the human body.
