This may seem a very bizarre request! I am Canadian and my great-grandfather Thomas Carter is quite probably the son of John Carter (apparently a notorious murderer from Watchfield, Bershire, England). I came across an article online which indicated that the Bershire Records Office (BRO) houses a collection of records from the Reading Prison including four photograph albums of prisoner "mug shots" for the period 1883-1915 as well as other Reading Gaol records / nominal registers.
John Carter was found guilty of murdering his third wife Rhoda (Titcombe) Carter in Watchfield, Berkshire in 1893 and was hanged for the crime Dec 5th, 1893. I'm looking for the photograph if it exists and information regarding the trial (supposedly the nominal registers would include the prisoner's name, time and place of the hearings of their case, their offence, sentence, personal information etc.) If a record of him is found I would love the information/ a copy.
An unusual look-up I know!!
