does ancestry dna matches only use dna infor or does it get into your family tree.

reason why, about two hundred years back I lose the surname trail but in the matches other trees that I match goes pass the 200 years. I think about 200 year back, Im the bastard child so I wonder if its being followed on the females side of my surname.

my y dna does not match my surname but ancestry still pulling my surname in other trees.

They do not use your family tree for DNA matches. If you have a DNA match, it is matched through DNA and not your tree. They do use your tree to put you in DNA circles with your DNA matches that have a common ancestor in their tree.

You share DNA with everyone on your match list. The family trees are only used to see potentially where that shared DNA comes from.

There are many possible explanations for this. It could just be coincidence, especially if it's even a somewhat common surname. Just because someone has the same surname in their tree doesn't necessarily mean that's how you relate.

As for your Y-DNA not matching your surname, this could be the result of a non-paternity event, or it could just be that your Y matches share an ancestor from before the surnames were established, therefore meaning different descendant lines picked up different surnames. If you know it was a NPE, depending how far back the NPE was (200 years? I'm not clear if that's what you're saying), you could still expect to have cousins also descended from that NPE, meaning they would have the same surname as you.

around 1850. my relative in a household with others, big family. my y dna does not match other relatives from that same household. Not even close. my y dna has not a single hit with my surname, but I got thousands of matches with another surname. ( im friends with another same surname, that can trace back to same household, his y and mine are totally different)

so there a NPE, a bastard child, an adoption. a unwed mother keeping her madian name, ok

so now on ancestry, Im getting hundred of matches that included trees that go past 1850 with my surname.
so adoption is out.

my theory is that since ancestry is not a Y test then its following the female side

FYI on the y test, Im at 111 markers and big y , over the last 10 years not a single y match on my surname.

so my question is, if i never posted a tree, would i still get those matches

Maybe, but like I say, there's still going to be people descended from the same event with that surname and like your tree, they will have trace the surname beyond 1850.

And some of those might just be coincidence and your shared DNA with them might be from a totally different branch. Do ALL those hundreds of matches descend from the same ancestor? Or do they just have that surname in their tree? You can't assume a shared surname means that's where your shared ancestry is, unless it's a rare name.

AncestryDNA is an autosomal DNA test - that means it includes DNA from your autosomal chromosomes 1-22 and the sex chromosome (23). Autosomal DNA is inherited from all your ancestors, male and female.

Yes. There are plenty of people on AncestryDNA who have never added a tree and they come up as DNA matches to me (and me to them). Have you not noticed the amount of people on your DNA match list who don't have trees?

This is so annoying, but if you upload your raw data to GEDmatch and use their subscription option tools you can see what actual shared DNA your matches have (not just the amount) so you have an idea how you are related.

There are even fewer people on Gedmatch who upload a gedcom (tree) in my experience. So while Gedmatch does have a chromosome browser and you can see who matches you on certain segments, that itself won't tell you how you are related. You still need the family trees to identify a shared ancestor.
