Earliest Locations
The earliest records found show the family in the south of England in Devonshire. Several early references place the early 's in the famous Dartmoor, in the villages of Chagford, Moretonhampstead, Hennock and Bovey Tracy.Those who migrated to Ireland, settled in the south of Ireland for some time until the early to mid 1800's when they started moving away. The family appeared to be based initially in Bandon in County Cork and County Limerick which is in the south west, but then moved to the Waterford area - near Cork further east. Note that the only spellings of the name found in Ireland are Clampett and Clampeth.
The family seems to have prospered in Ireland, having a large family home as well as a holiday home on the coast at Dunmore East in County Waterford. I have seen photographs which I am trying to obtain to place on the web site. The family were apparently involved in the local cottage industry of glass making and the story goes that they were among the founders of Waterford Crystal.
