Now, there are a couple of good solid American names. I bet their ancestors lived right alongside my ancestors at the Massachusetts Bay colony. Mhm.
I doubt those were their "American" names.
Don't be too surprised. You know the story about the pilgrims (on their hajj but they got lost) meeting up with Samoset bin Abedin, the native American muslim and being so surprised he spoke English. He explained that he had learned it from his hajj to the mosque at Jamestown, the 23,345th most holy place in Islam.
