Winterbotham Family Genealogy Forum
Apologies for recently posting the wrong message under this topic.
Rose's mother was Mary Rose Collins who married Washington Lafayette Winterbotham on 22nd July 1862. Washington Winterbotham was a general practitioner / family doctor. I am afraid I have no other information on Mary Rose Collins or Maria Acton, but I have plenty on Rayner Winterbotham and his very interesting family.
Assuming you live in the U.S., you may be interested to know that Rayner's father wrote a History of America while in Newgate Prison for sedition in the 1790s!
