From Cornwall They Came:

Following the decline of the mining industry in the mid 1800ís, many Eustis, Eustice & Eustaces from Cornwall took their mining skills to the USA, Canada,

Australia and elsewhereCornwall located in the extreme southwestern part of England, is bounded on the north and northwest by the Atlantic Ocean and the south and southwest by the English Channel. The County of Devon borders on the east. As early as the 17th Century, the village of Crowan in Cornwall developed into a thriving mining town where the Eustis/Eustice/Eustace family became very evident.

Cornwall was the most important metal mining county in the entire United Kingdom. In fact, it had the longest history of continuous production and a total value of output that dwarfed its nearest rivals.

While having immense copper and tin deposits, Cornwall produced a wider range of minerals than any other district (it was the only source of some of the rarest minerals) and was the only region to see large-scale mining continuing down to recent times.
Lead and silver deposits, which dominated the non-ferrous mining of the Pennines and Wales, were less plentiful but Cornwall briefly claimed Englandís largest single lead mine ó East Wheal Rose ó in the mid-1840s. Together with associated districts, Cornwall produced nearly all of the Englandís tin and arsenic and most of its copper.

The tin from Cornwall has been mined and worked since the Bronze Age. One of the largest tin mines was located near Camborne, where many family members lived. Copper mines are located in the St. Just and Carn Brea regions. In 1851, the mines of Devon and Cornwall were estimated to produce one-third of the copper mined in Europe.

During the eighteenth and early nineteenth centuries, Cornwall pioneered deep mining and steam pumping technology and its miners and managers were eagerly welcomed in mining districts throughout the world.

For a number of reasons, the Cornish mining industry began to collapse in the mid to late 19th Century. Though some remained in Cornwall, many Eustice, Eustis and Eustace namesakes scattered all over the world where their mining skills were in strong demand.
