William Strachey, a secretary of the Jamestown Colony, wrote in "The History of Travel into Virginia Britannia" in 1612 that there were reportedly two-story houses with stone walls at the Indian settlements of Peccarecanick and Ochanahoen. The Indians supposedly learned how to build them from the Roanoke settlers. There were also reported sightings of European captives at various Indian settlements during the same time period. Strachey also wrote that four English men, two boys, and one maid had been sighted at the Eno settlement of Ritanoc, under the protection of a chief called Eyanoco. The captives were forced to beat copper. The captives, he reported, had escaped the attack on the other colonists and fled up the Chaonoke river, the present-day Chowan River in Bertie County, North Carolina.
