This update shows a new branch called I-BY160643. One of the members has French-Canadian paternal ancestry, he did the Big Y-500 test several years ago. Genealogy records in Quebec and in some areas of France are very good, and he was able to trace his paternal line back to France, and he was able to identify a male-line descendant of the same family who was born in France only 20 miles from the town of the ancestor who went to Canada. He arranged for a Y37 test for the Frenchman, and when they matched he arranged for an upgrade to Big Y-700.
The French-Canadian man and the French man have different surnames, it was common in Quebec for surnames to be changed, but these changes were recorded in the baptism, marriage records etc.
These two men have a number of unique variants/SNPs that's consistent with a common ancestor who lived approximately 500 years ago.
At this point all other men in I-A8742 have British paternal ancestry. But I-A8742 is rare and there has been little DNA testing in France.
