Help still required

Hi
I've been involved with local history all my life and with the history of St Leonard's Church, Middleton, Manchester, for a couple of decades. I am currently writing (or re-writing) the history in time for the 600th anniversary of the rebuilding and reconsecration of the church by Cardinal Thomas Langley, Prince Bishop of Durham, in 1412.

I am looking for any documents relating to the church and for someone who can translate old English and also Latin contained in old documents.
Is anyone out there, please?
I have been listing the history in chronolgical order and this can be viewed at  http://docs.google.com/View?id=dc9xkfjz_148gxsts2ds
