Is everyone a crypto Jew to you?

The name Lord is part of the ancient legacy of the Anglo-Saxon tribes of Britain. The name was taken on by someone who worked as a hlalord which meant keeper of the loaf. This person was responsible for supplying food to those under his care. Occupational names that were derived from the common trades of the medieval era transcended European cultural and linguistic boundaries. Occupational names have remained fairly common in the modern period. This is attested to by the continuing appearance of occupational suffixes at the end of many English surnames. Some of these suffixes include: herd, monger, maker, hewer, smith, and wright.
