Hi Aline,
First, I'm guessing that you are from or have ancestors in Quebec - your name looks very French Canadian to me. As answers to DNA questions can be very contextually dependent, I'm going to assume that context. Quebec is special due to the founder effect and endogamy (see: https://isogg.org/wiki/Endogamy ... ISOGG is a very reliable resource for DNA genealogy guidance & info).
Also, if French is your mother tongue (just guessing), feel free to ask questions in French. WikiTree can be multilingual. And there are several francophones and others with more modest French skills.
You state, "the names for the parents of my ggm are not correct on Ancestry" - what do you mean by that? It really isn't clear to me. I could interpret that a few ways:
- A record of the birth for your great grandmother has parents listed whom you believe (for some reason?) are not correct.
- Some user (i.e. an amateur genealogist) on Ancestry has a family tree that includes your great grandmother and parents for her. You believe those to be incorrect.
- Your DNA evidence suggests a different set of parents for your great grandmother.
For Quebec (again, guessing), the parish records tend to provide highly accurate family information, but there are still missing pieces. It helps to (re)construct as much of your family tree as possible using those records, along with censuses and other info, then check to see if what you have is accurate based on DNA matches with (distant) cousins.
In the case of a roadblock (dead end, or brick wall) in your family tree, to start solving that you need to start by assigning DNA matches who are connected to the ancestors that you already know. That leaves ones more likely to be connected to the mystery ancestor(s).
So I would suggest to start by adding as much of your family tree as you already know to WikiTree. Document where the uncertainties lie -- some like to add a "Research Notes" section to a profile to write out the mysteries and questions -- and then start figuring out how DNA matches connect to your known ancestors. You might need to build out the branches to include some of those cousins.
DNA can be very confusing as someone with French Canadian DNA. Everyone's related about 100 ways, just in the past 15 generations alone! So one needs to triangulate matches carefully. WikiTree is the perfect place to do this. I've explained in a comment elsewhere before, so I'll paste what I wrote before as an example to a user named Mike:
People with French Canadian ancestors generally share multiple common ancestors. And, thanks to digitized Quebec parish registers (and the PRDH), it's possible to create a very complete family tree, going back to the 1600s. Usually one doesn't need to work that far back because most French Canadian ancestors up to the 1700s are already on WikiTree. So it's just a matter of connecting things up.
Given that, imagine that we have two random-ish Canadians with Quebecois ancestry: Paul Martin Sr (1903-1992) and Pierre Elliot Trudeau (1919-2000). And let's imagine that they share 1 segment of DNA. If we pop them into the relationship finder, we see that "Paul and Pierre Elliot are 6th cousins once removed", but that isn't just one couple from whom the DNA could have come: there are a total "48 common ancestors were found between Paul and Pierre Elliot within 15 generations." ... so we actually have a lot of options!! And that's too much for one to confidently assign a segment here.
But... WikiTree has your back, Mike! Built-in, right on that page, you have the "Advanced filter"... so you can "Enter one to three additional WikiTree IDs, separated by commas, to limit the common ancestor list to those who are also ancestors of other people." So we can compare with a 3rd WikiTree member who matches on that same segment, Mr. René Lévesque (1922-1987). Now we pop in Lévesque-383 into that advanced filter and now it says, "5 of the common ancestors were found to also include René Lévesque." Now we're getting somewhere. We would probably need to check with a few other DNA matches who match on that segment and who have trees, and we will narrow it down to a particular couple. Case in point, we happen to also match Mr. Pierre Joseph Olivier Chauveau (1820-1890) on that same segment. So we add Chauveau-24 into the filter and now we have narrowed it down as far as we can go: "2 of the common ancestors were found to also include René Lévesque and Pierre Chauveau" . Yes, we are down to just one couple: Charlotte Maugis (1607 -1676) and her husband Pierre Miville (1602 -1669).
Of course, you need reasonably complete family trees here. But that is feasible for Quebec and probably also for certain groups of early American settlers. (It would also be cool to have a less precise version of this, for those with less extensive trees. Perhaps resulting in a looser match if you have terminal ancestors in the 1700s or 1800s from the same geographic region.)
This also requires that you or your DNA match builds out all of his or her French Canadian branches. But that's the point of this proposal. Make it easier to invite our DNA matches to participate here on WikiTree.
Personally, I have some French Canadian DNA matches who are quite distantly connected, yet we share a lot of DNA. So having them (or perhaps profiles for those matches' grandparents or a specific gateway ancestor) allows me to do some filtering and figure out how we are likely related. For those more distant matches, one generally needs to source one segment at a time. So learning to use DNApainter (https://dnapainter.com) is a wise idea.
I hope this isn't overwhelming... but it's a surprisinly
