Genetics to the rescue of the genealogy

Our genes are like a big book of history…

Research of our ancestors with the civil registers, monographs, notarized contracts is often a long path strewn with frustration. Paper documents are often unfortunately destroyed by fire, flood, mold or simply lost. It is not uncommon to find unanswered face in search of ancestors of individuals who share the same family name yet.

The discovery of Kary Mullis, Nobel Prize in Chemistry in 1993, has revolutionized genetics. He discovered a method to produce as much as desired DNA from tiny particles of tissue, such as hair or even a single cell. Practice of genetics has grown considerably during the last decade, allowing an analysis of DNA from a few cells deducted from the surface of the oral mucosa.

Genetics is thus to rescue the genealogy is the genealogy genetic or molecular genealogy or génétéalogie. We see the use of such tests in the novels where, thanks to modern DNA is identified as a criminal exonerate the accused. It is also widely used tests are for verification of authorship. It is through genetic genealogy that could certify that George Washington had a child of a black slave.

Chromosomes in humans are microscopic elements consist of a DNA molecule chromosomes carry genes that carry the genetic message transmitted from parent cells to daughter cells. Chromosomes are represented by pairs in parallel with their counterparts. Chromosomes in humans are number 46 or 23 pairs of which 22 are homologous chromosomes pair and the last corresponding to the sex chromosomes called X and Y. The man has a Y and an X on the 23rd pair, one X from the mother and a Y from the father. Mother on her 23rd pair shows two X chromosomes so the mother can give to his descendants that X. The Y is passed from father to son. It is this DNA Y which is used in genealogy since Y-DNA is passed from father to son with rare mutations. Thus, my first male ancestor arrived in Quebec should have the same genetic fingerprint as me. In addition, a person named FOREST FOREST or or or FORREST OF FOREST should show the same markers as me if a descendant of Michel de Forest. Otherwise, you must understand that it is the descendant of a family or other there was a break in the lineage. This analysis is restricted to men only.
Here’s a hypothetical example:

In this example a single common marker indicates that D. Forest and G.Forrest are not connected. They may have a common ancestor, but it goes back thousands years.

For women, there is the possibility of an analysis of the mitochondrial DNA is passed from mother to daughter. The mitochondrial Eve would have lived there 150 000 to 200 000 years in East Africa. It would be the ancestor of all living humans on the planet today. According to Bryan Sykes, the mitochondrial Eve would have had seven daughters (Jasmine, Velda, Ursula, Tara, Helena, Katrine and Xenia) who migrated from Africa to Eurasia. The analysis of mtDNA allows us to connect to one of them.

Approximately 32% of the entire database mtDNA haplotypes belong to the group H, and about 21% of it would type 519C. So, my matrilineal ancestor Helena (haplo group H) had lived there about 20,000 years in the south of France, in the Rhone Valley.Helena’s descendants were most numerous in Europe. It is assumed that this clan of hunters was born 20,000 years ago in the southwest of France, Dordogne, and that his descendants migrated gradually towards the north and west, colonizing as Brittany and the British Isles ago 12,000 years. This analysis shows my matrilineal European origins.
There is a major project which is aimed at French-Canadians DNA project French heritage (www.frenchdna.org) in which we find the surname Forest. The French Heritage DNA Project is open to all those who think they have French ancestors, even distant. So if you’re in France, the former colonies of French Canada, Acadia, or that you are Métis, Cajun, Creole or among your ancestors he was of French descent, this project should interest you.

This project is dedicated to the hundreds of founding ancestors who left France in the 17th century to establish colonies throughout the world, especially in North America.We who honor the name of a French family owe it to these brave and proud settlers and their descendants.

There are also those brave women who have not left their name because it was not cultural usage, but have left their genes and maternal love. This project is their equally dedicated and will try to find them by following the footsteps of mitochondrial DNA (mtDNA) they have over successive generations passed from mother to daughter, mother and children both sexes.

Already several family associations, as Daigle, the Beaugrand, the Delamontagne the Foster, Forrest gave their approval to these projects for genetic analysis. It is therefore hoped that the Forest will follow suit in this gigantic undertaking of reconstruction of the human genome world. Should be as Forest, Forest, Forest Forrest and the various regions of Canada and the United States participate to better write the history of our family is in our DNA.

Several companies offer reliable Pleiades testing at prices ranging from U.S. $ 99 to U.S. $ 1000 depending on the amount of testing required. A basic test of Y-DNA 12 marker or the ADMmt costs around U.S. $ 110. These tests may be ordered directly online on the website of the companies that offer this service.

The following companies offer this kind of test:
