Have found John but spelt with 2 LL
John Mullhearn, age 24, Killed in Strafford Main Colliery/1 Park Row, New Street,buried 19 August 1894, Section T Grave number 361.
If you were to contact Barnsley Crematorium (they hold the burial records for the cemetery)they will send you a map of the Cemetery and the Section T with the grave marked for you so you can at least work out where it is.
