Sorry I don't have any information for you but I too am wondering why my grandmother and her brother were put in an orphanage. They were from Johnston County, North Carolina and lost both parents to influenza in 1917. They were both put in a home despite the fact that half of the farms in the township and neighboring townships had both their father's surname and their mother's maiden name. I can't imagine why they weren't taken in. It was difficult for me to track them at first because my grandmother's maiden name was Maiden (at birth) but the orphanage for some reason changed it to Maydon!
