Hi Graham,
Depnding on the crime he was hung for, and a variety of other factors, he may well have been buried in consecrated ground; possibly in his home town or village.
I researched a similar case from a similar period some years ago, where a man had been executed for burglary and handling stolen goods. As his crime did not involve the taking of human life, his body was released to his family, and he was buried in the family grave, some 40 miles from the scene of his execution.
