There is a price advantage in joining through a surname project, and you may join as many as you like. We hope to link all submitters to Jehan Terriau, who was born about 1601 in France and died in Acadia (present-day Nova Scotia). The most intriguing result will be to distinguish the various lineages by small mutations that are passed on from father to sons down the male-only line. If you have a Terriot ancestor within four or five generations, you might also consider testing your autosomal DNA through the Family Finder test. This might link you to other cousins with the same DNA in the Terriot (and variants) line. Both men and women may take this test. For more information on DNA testing and many other topics relevant to our family, visit the Terriot Acadian Family Society website at: www.terriau.org. The Family Tree DNA web site is also very informative on a variety of DNA topics.
