Harley before 1964 it id more than likely be hockley cemetery.Depending on where in Hockley, they lived you have witton cemetery or lodge hill cemetery, warstone lane as well. If you go to the library in Birmingham they have them all.
if you can not just give me the name and I when they died and I will find it out foryou.
Over the last few months I have found out alot about my family and have found almost all their graves.
