I have just been searching on the British Newspaper Archive and found a great article which involves my ancestor as a witness in a "charge of attempting to poison". The other witnesses are a Richard Blackler and also a Charlotte Tapson and Eliza Jane Tapson.
If anyone would like me to send them a copy of the article, let me know! It's great because it has these people's actual words they said in court.
The date is 1860 and they were servants at a house in Ipplepen, Devon.
