The “Rolst Hole” that you refer to is in fact, Rabbit Hole or Rabit Hole. The entry Book 53 p115 is a gift made in 1825 of a mine in Middleton Wood at Taintor ranging down to the bottom of the valley at Hollowchurch Way. So this is not relevant and is a mistake by the barmaster. I dealt with the mines on the Nimblejack including Taintor in PDMHS bull vol 5 part 3.
Rabbit Hole Mine is only mentioned in Book 53 p107 in a gift dated 17 Jan 1825 to Mr. Thomas Henstock of old ground from the top of Ible Wood above the Comp, viz 3 E-W veins from the corner of the top fence above the Rabbit hole with 16 meers W and from the same east down to the bottom of the wood. Also all cross veins from Bonsall Leas to George Halls title westwardly.
[I do not know what “the Comp” was, nor does Jim Rieuwerts, who happened to phone me last night.]
Exactly the same title was given away again in 1831.
There is nothing that I know of directly relating to Rabbit Hole Mine.
