Decker surname meaning

Decker is chiefly a German and Dutch occupational surname for someone who covered roofs. Depending on region and period, that work could mean a roofer, thatcher, tiler, slater, or shingler. The name is related to German Decke, “covering,” and to Dutch Dekker. Decker, Dekker, Deckert, and nearby spellings can therefore appear in the same family’s records without making them interchangeable in every case. A less common proposal connects Decher with the number ten, possibly a tenth child, but it is not the main explanation. The catalog classifies Decker as occupation with high confidence because the roofing sense is direct and independently documented.
