I've been on a search for those who carry mtDNA of Milly Riddle Hitchcock(my 4th Great Grandmother). You can read more about the reason in my earlier posts. Only females are capable of passing on the mtDNA to their children. Although he would have never been able to pass the mtDNA on, Edward was a carrier of Milly Riddle's mtDNA. His mother Omelia was the daughter of Rebecca Hitchcock and Rebecca was the daughter of Milly Riddle Hitchcock. He died at 23 years of age of diabetes mellitus.
