They have a police identification file and this will provide the names and page number. The staff will help you. You can then fill out a slip of paper to obtain the album which is fascinating. The album is massive and comes in a huge box and this is a real treat to look through. The photos are of very good quality and I am sure it will be a real treat to see your ancestors in this way. (I know I was highly delighted to see my ancestor Jacob.)
There are two photos of John George and one of Orselina/Lily. There will be one of her husband to be too who had the name of Robert Guthrie. They were jointly involved in a crime and sentenced to hard labour.
If you take a camera I would recommend paying for a day photography pass (I can't remember exact charge but I think it is no more then £10 to - £16) - then you will be able to take photos of these photos and any other records which interest you. However, you also have to sign a short form and agree not to pass on the photos to other parties as I remember it.
You will also be able to order the workhouse records!
The dates on the photos in the album are the dates people were convicted. The only bad thing about visiting the archives is that time goes too quickly when you are there - a whole day can seem like only half an hour.
I would also recommend a visit to the North Shields library, local studies department and you will be able to see the Shields Daily News on microfilm which recorded many of the trials, including those of these ancestors of yours (as well as some of my ancestors who appeared in court cases). This library also has some of your ancestors burial records - however you will also be able to see these at the archives. In the city centre of Newcastle is the library where you can view your ancestors death notices (and some burials). Check the times - but on some evenings the library is open until 7 pm.
I know it will be hard to fit everything in in but this is just to let you know what is avaiable. It will be very easy for you to access the criminal mugshots album - the staff are very helpful.
I hope you have a brilliant time!
