Well this is a bit embarrassing. Of the pages that I've transcribed so far, I've only missed one - and it's the main page for George Harrington. He was admitted to the Reformatory between 29 Oct 1863 and 9 Nov 1863. Although I don't have the main page, I do have the details from the next page, which is additional information. The parental address seems to have been Darley's Yard, Gooch Street, in Birmingham.
June 7 1866 emigrated to Canada
August 1867 heard from boy near Richmond junction, Canada. Doing well.
November 1869 ditto
January 1870 ditto
April 1875 heard from boy from Valley Fields Paper Mills, Canada, P.Q.
The admissions register is held at the Central Library in Birmingham City Archives. If you contact them, and ask them to look it up for you, they may oblige. It is in the first Admissions Register, entry no. 265.
Sorry about this - I will have to get the details myself next time I am in Birmingham!
