Martin, I hope you find it.

As posted before, 'piner' is in the complete Oxford English Dictionary, with the definition I gave, 1. a labourer; "now in N. E. Scottish dialects applied to a man who cuts peat, turf, etc." Quotations are given, some medieval.
The old spelling was pynouris or similar.

Maybe someone can translate this entry, which looked interesting- 1572, Knox: Sa scho wel lappit in a cope of leid and keipit ... unto the nyntene of October, quhen scho by pynouris wes caryed to a schip, and sa caryed to France. Sounds like a body is involved.


There are other meanings given in the OED-
One who pines.
A worker in pine, or one who logs pine (U. S. and Australia).
One who inters the dead.
An animal suffering from a wasting disease.
A tormentor.

Pinery- a pineapple plantation.
Pinery- a grove of pine trees.
