The earliest grand houses on the east side of Durham were built along Roxboro and the first two blocks of East Main St. east of the intersection of those two streets. Some of the early, more forgotten names in Durham history - Day, Lyon, Fuller - industry magnates who faded from the scene as business consolidated around the Blackwell/Carr and, later, Duke empires. Few records of these early houses remain, except for intriguing footprints on the early Sanborn Fire Insurance maps, and most of them did not survive the early 20th century.
