Captain Thomas Armstrong
Captain Thomas Armstrong was a chief of the Turtle branch of the Delaware tribe. He was said to have been a white man who had been stolen when a mere child and was raised by the Delawares and adopted into their tribe. Other authorities say he was of mixed blood. He was the chief at Greentown and was aged when he was forced to leave the village. All the Indians, however, at Greentown were not Delawares. There were a few Mohegans, Mohawks, Mingoes, Senecas and Wyandots there also.
