From Herbert Fox Bio[[1]], some reference to Marianne. Check with Michael Phillips
(How do we know she is the mother of Herbert or the wife of Charles. Is Charles fictitious, is Marianne. If she was a spinster then who is Herbert's Mother? Need some more research to ascertain who Marianne is and if she is Herbert's mother - Mention of a spinster is confusing ??? Phillips-4328 04:05, 16 April 2014 (EDT) )
