Just a thought, my gt grandfather was born in the Trysull and Seisdon Union Workhouse, which 'serviced' a big area including Codsall and Tettenhall in around 1860. I wanted to find out more from this institution's records, and was advised by Wolverhampton Archives to visit the Stafford
Records Office, where all the records are kept. Hope this may help, I haven't visited there yet, so don't know what details the records show.
