The miners of Cornwall and Devon were probably much more mobile than the
agricultural workers of the same two counties. Ore fields were discovered,
worked and then abandoned, so miners moved around the area to where the
work was. I am therefore not surprised to learn that only two of those
drowned were from the parish.
Although genetic evidence does not give a definitive answer to the question
of mobility in medieval times, it does indicate certain geographical
trends. For instance, the highest concentration of the typical Germanic Y-
Chromosome signature is still to be found in the region of the Danelaw. If
large-scale population mobility had occurred, one might expect to see a
more homogeneous distribution of genetic signatures than is apparent from
