Hello,
Birmingham Central Library - Heritage and Archives, should have burial records and plot numbers for Witton Cemetery.
They may also have for Warstone lane Cemetery too.
When were you thinking of visiting Birmingham ?
The Friends of Key Hill & Warstone Lane Cemeteries in Birmingham Jewellery Quarter hold an open day every year in September.
This is a fun day out with guided tours , stalls , local Authors, entertainment , Cemetery Records.
I will do my best to help regarding Warstone Lane Burial.
