Dear Julie: I am researching the life of Edwin Tappan Adney of Woodstock, NB, my wife's grandfather (1868-1950). He did extensive research on the Adney family, but never published it himself. He did share it with John R. Adney of Miles, Iowa, and John R. shared it with Dennis W. Emmers of Columbus, Ohio. Mary Alice Claycombe Adney copied this material in October 1985, and has published some genealogy that summarizes the work of Edwin Tappan Adney, with some additions and corrections by John R. Adney. Mary Alice's address is 214 South East Parkway, Richmond, IN 47374 (as of 1986), and she may be able to supply you with a copy of her publication.
Although there was a Charles Adney (son of Thomas, son of Thomas), born probably 1803, I can't tie him in with your family
By the way, I also suggested that there be an Adney Surname on GenForum, and I'm glad it is here. In the course of my research for the biography, perhaps I will be able to get Tappan Adney's notes in better shape for presentation.
