I would like to exchange data with you, but I am afraid that most of my research has been on Thomas W. Duncan and his father Stephen C. Duncan. Thomas and Delilah's daughter Mary Duncan married my great grandfather Amos Thornsbury Vineyard August 16, 1866. Mary died December 8, 1930 in Saline Co., Illinois. I have compiled a lot of data on Thomas and Delilah's children. My file on Wambles contains two articles from Springhouse Magazine in 1984. These records were furnished to my cousin by Ruth Cavender of Drayton Plains, MI. I have tried without any luck to find census records to support this article.
