http://genealogy.about.com/library/blchattrans-roderick.htm Dr. Thomas H. Roderick was speaker for SHELDON FAMILY ASSOCIATION about MTDNA in 1996. He was very involved in genealogy testing. He was often a speaker at National Genealogy conventions also where I often sat with him in other workshops. http://genealogy.about.com/library/blchattrans-roderick.htm is a site where he was asked and answered questions. This may be of help to people wondering about MTDNA.
