y-DNA
Scientific research throughout the world has shown that all our paternal lines are connected somewhere in the past and that these connections can be traced through yDNA. As with maternal genealogies defined by mtDNA, men tend to cluster into a small number of groups, eighteen in total, which are defined by the genetic fingerprints of their yDNA. In native Europeans, for example, there are five such groups, among Native Americans there are four, among Japanese and other East Asian people there are five, and so on. The men within each of these groups are all ultimately descended from just one man, their clan father. These ancestral clan fathers were not the only men around at the time, but they were the only ones to have direct male descendants living today. Other men, or their descendants, had either no surviving sons or only daughters. These clan fathers in turn had male ancestral lines that ultimately converge on the common paternal ancestor of every man alive today. This man, known as “Y-Chromosome Adam”, lived in Africa 60,000 – 80,000 years ago. For our classic Y-Clan service, we read twenty-six elements of your yDNA fingerprint and build up a signature. By comparing it to thousands of others from around the world, we are able to deduce your paternal clan and your ancient ancestral father. Not only will we be able to tell you from which ancient clan father you are descended, we will also give you some information as to when and where he lived. The genetic elements of your signature also change over the generations and by comparing your genetic signature with those of others it is possible to tell, on the balance of probability, how closely you are related.
Joseph Corey submitted his yDNA to Oxford Ancestry. The results confirms the Norse Ancestry with High Confidence. Interesting discussion of Norse control came to an end in 1472 when the Isles of Orkney and Shetland reverted to Scottish sovereignty. For anyone on the John 1 line, this should save you about ￡500. Joe has furnished three reports: Results, Analysis, and Y-Clan Interpretation.
Bill Corey, descendant of John Corey of Roxbury,is one of the original subjects of the Cory Family Society yDNA testing back in the 2000s. That testing showed he is in the John Cory I line, and that has been confirmed at FTDNA with Y-67. David A. Cory has spent a lot of time looking at Bill's ancestry, and has circumstantial evidence that his earliest known ancestor, John Corey of Roxbury, MA, was a grandson of John Cory I. John Cory I had three grandsons named John. One was John Cory III, ancestor to Joe, Mark, and David. He was the son of John Cory II. Another grandson died in Southold in 1754. From his will and other evidence, David believes he was a son of Abraham Cory. That leaves John, son of Jacob. He may be the John Cory who married Mary Griggs in Roxbury, MA in 1713. David plans to finish an article on the first 3 generations of American Corys that lays out all the evidence. Look for it in a future newsletter.
