DNA Signatures - Adding your signature to the catalogue

There are 2 kinds of signatures : triangulations and references or candidates.

A signature is triangulated when 2 DNA tests (or more) are linked, these tests are coherent and the relevant genealogical lines are documented.

Otherwise, a signature can be used as a reference or candidate to find more triangulations or to complete a triangulation.

Documentation required

The genealogical lines should be documented. This means :

Join a project

It is a good idea to join one or many projects because this will increase the usefullness of your DNA test and your visibility when looking for matches (i.e. to attract more people to complete the triangulation) and you get also a rebate on some DNA tests.

As an admin, I suggest obviously to join the French Heritage project. With a Quebec pioneer ancestor, I also suggest the yDNA and mtDNA Quebec projects. With Acadian roots, there are some Acadian projects, one suggested is Acadian Heritage which I manage.

May projects are for a family name. Also, many groups are haplogroup-oriented (yDNA and mtDNA). If you made a Big Y test, the specialized groups will help to better define your paternal line.

To join a project from FTDNA, you must first have an account. This will eventually give you a rebate or a mean to perform some tests not available otherwise (12 and 25 STR in particular). Each project is independant. By participing to many projects, you incease your visibility and your odds to have someone else tested to match your DNA signature and to get a match. You can also offer a free test to find that match.

FTDNA Dashboard

From your dashboard (or profile), please perform the following operations:

Do it by yourself

A DNA test from FTDNA has 2 main groups of results : DNA data and matches. DNA data is used to find relatives among other users of the lab.


From your dashboard, under [Y-DNA-Results Completed], select [Matches]. You get the list of matches or Y-DNA cousins. Keep in mind that the common ancestor may be living 1000s years ago but genealogical records are from the 1600s and family names in France are from 1200-1300. Find those with a similar name to yours (or a dit name) with a genetic distance not too large. Then, if the name is in blue, click on this name. If the name is in black, however, data are not shared.

Y match

If you have many matches, you can filter the results for [The Entire Database] or a specific project. You can focus on a family name or on an area. Participating to a project is not compulsory but if you don't, the project manager (admin) can't help you. The field Markers will select the number of markers for the comparison. The distance allowed depends on that number. In some cases, someone may appear at 25-marker but not at 12-marker. This means there are differences in the first 12 markers but maybe none in the next 13. These differences or mutations are random.

You can display up to 1000 matches. By sorting on "Name", you will get the list by alphabetical order.

If the name of the person is in blue, more useful data is shown.


From your dashboard under [MT-DNA - Results Completed], select [Matches] to get your MT-DNA matches. The common ancestor may be thousands years back but genealogical records are mostly from 1600. Look for anyone under [Earliest Known Ancestor] for a common mothers ancestor having a genetic distance not too high.  Then, if the name is in blue, click on this name. If the name is in black, however, data are not shared.

There are 3 kinds of MT-DNA tests : HVR1, HVR1+HVR2 and FMS.

You can make a search depending on the tset you made. With an FMS, you can see up to 3 differences from your results. For teh 2 other, an exact match is needed.

The same results as for the Y-DNA tests except the TiP is not available.
