Hello and welcome Jacqueline. It's always difficult to pinpoint a grave especially if you don't know which cemetery. Firstly it depends on the year as cemeteries were opened in different years. Not many actually had memorials to 'public graves' as they were called later. There are several at Key Hill Cemetery in Hockley with names listed, there are some at Warstone Lane in the Jewellery Quarter and at Brandwood end and Witton Cemetery. The best place to start is at Birmingham Library with the actual burial registers if you find the person listed in a paticular cemetery you have a place at least. You must know the actual date of death to search, or it will take forever. Many of the public graves have been covered over and there may be other burial's on top this was done in Victorian times and later as space ran out and it became a health problem to bury people, especially if there had been an epidemic. If you look on the Key Hill thread, I have posted some examples of pubilc graves.
