Thatcher or roofer
Derived from the Middle Dutch word 'decker', this name originally served as an occupational surname for someone who covered roofs with straw or tiles. It shares the same etymological roots as the more common German surname Decker. In a modern context, it is increasingly used as a distinctive first name with a rugged, industrial feel.
