Thanks Jennyann, I'll have to go into Erdington Library and ask about what's stored in the basement.
Yes, Mr Meacham's papers were typed up by his son after his father's death, and are bound in 2 (or more) volumes, which can be borrowed from the local history shelves in Erdington Library. I've taken a photocopy for personal research. BEWARE: Helpful though this material is, the areas of my own expertise that I have checked out are riddled with errors - there are copious extracts from directories and censuses, etc that were not so readily researchable years ago, and the association between people and buildings is highly inaccurate.
Incidentally, I know that there is a photo on microfilm in Birmingham Library of the Elizabethan Moat House, because I've looked at it there, but it has never been published or made more widely available, which is a shame.
