There's more,Jane:-
All except the 1943 burial are probably recorded at:-
Rose Hill.
Cantley Lane,Doncaster.DN4 6NE.
01302 535191.This is the local crematorium and cemetery.There may be a charge for researching.
Hyde Park cemetery closed for burials in c 1960,unless someone in the family aready had a grave.
However Rose Hill also has their records.
Good luck.
