There are some cool techniques you can use to build a tree with DNA information on people you don't know, but it definitely will not build a tree for you.
Really helpful video, thank you. I'm from Spain and was considering doing a DNA test myself but after watching some videos of spanish people sharing their results on youtube I noticed most of them got a very high "iberian" percentage (higher than 90% sometimes) so I though no much information I would get then as I know that my parents, grandparents, great-grandparents, and great-great-grandparents are from Spain. So, worth doing it?
If you are interested in genealogy and finding ancestors and cousins, there is no better use for your money. If all you want is ethnicity results, there is no better waste of your money.
9:38. You are correct about that! I have several 7th & 8th cousins that is predicted to be my 4th Cousins on Ancestry, especially on this one particular part of my maternal grandmother's family tree. Some of them even match me with Very High or High Confidence. Also, for some strange reason these 7 or 8th cousins share more DNA with me than some of my closer cousins on this particular side. Some of my 4th or 5th cousins and sometimes 3rd, are predicted to be Distant Cousins of mine rather than close cousins. Strange!
I got over 5,000 matches above 20cM on Ancestry, but I'm not very surprised at the high number because all my recent ancestors had lots of children. Fortunately I've been able to identify a lot of the matches and even some of the more distant ones.
Wow!! For me I only have 4 1st cousins and about 16 2nd cousins and I am close with basically all my 3rd cousins. I guess because I have a pretty small family
Lucky you. Genealogy must be easy...except that is so much fewer people to ask for information, so less memories to combine together. I guess you can't win either way.
Talk about small! I've no 1st cousins and a major brick wall as to my maternal grandmother's actual parents. Kind of wish DNA testing was mandatory, esp. in Ireland. : ]
Luckily my paternal grandfather came from a large coal-mining family (Staffordshire, England). Big problem is that my (Dublin Ireland) maternal grandmother was told she was an orphan' (probably she wasn't); can't be sure the names given as parents on her birthcert. were real. Easy to see why I'm an advocate of DNA testing.
"120 first cousins". Holy lordy! The name of the grandparents must have been Mr and Mrs Rabbit. I have no first cousins. The result of a only child for one parent and a sole infertile sibling of the other.
I just spoke with a gentlemen last week who had 13 siblings. Almost all of them had 6-10 children. I had heard of another person in the area near me who was one of 20 siblings. Hate to see the food bill at that house.
My heritage gave me 2,000 DNA cousins in UK where I Iive, and 8,000 in USA. I thought they got my DNA mixed up until I did my tree and found many British ancestors who had emigrated from 1600's, so I know they are very distant cousins with whom I share some DNA
I have quintuple cousins in my dna matches, and I’m having a huge issue with pedigree collapse. Oddly enough my mom’s northern us family is related to my dad’s Deep South family on several lines… I have 65k dna matches on ancestry, my brother has 74k. On MyHeritage I have 21k, and on Gedmatch I don’t even have a count. How do I use the Leeds method with pedigree collapse?
I know some of my 2nd cousins because my mom actually close to some of her cousins and hang out with them so i ended up getting to know my mom cousin kids. Some of my 2nd cousins were just as old as my mom. Now I don't know any of my 3rd cousins in real life but have met some on ancestry. One of my 3rd cousins kind of look like my 1st cousin I know. I imagine if I stayed close to my 2nd cousin our kids who would be 3rd cousins could actually get to know each other. I met a couple of my grandparents cousins but never the grandchildren of those cousins.
Thank you so much because I am 585 cousins I think about retesting because I didn't follow the direction properly At the time I took the test I just finish drinking a diet cola Maybe debt in a fear With the testing What is the possibility it could be accurate And I agree with everything you said Thank you
Welcome to the topic of endogamy. First, watch this video to understand the topic.

I find it strange that a lot of people don’t know their second cousins. My parents were close with their first cousins so I grew up with their children my 2nd cousins along with my own first cousins. I would guess if your parents weren’t close with their 1st cousins that that would explain why you haven’t met a single second cousin
Very interesting, thanks. So even after doing a test, even if you have NO link to a person you think is 3rd cousin or more distant, that DOESN'T actually mean you are not related. So the idea that an autosomal DNA test can prove or disprove a genealogical link above 3rd cousin distance is simply not true.
Can prove? Yes, it can with proper triangulation. Can disprove? No it cannot, because as you understand above 3rd cousins there are an increasing amount that we don't share DNA with.
My paternal great grandfather was the 14th child. Do the genetic problems associated with older paternal sperm affect the 50% rule? Does it play out in succeeding generations?
No, because you get one set of chromosomes from each parent. Whether it affects succeeding generations, I don't know, but I can't think of any mechanism that would influence recombination in later generations.
My mother has over a thousand 4th or closer on Ancestry. I also do and so do my brothers. Two of my daughters have over a thousand and one has about 750. Of course my grandfather on my mom's side had over 150 descendents when he died. His 14 kids had a lot to do with that! I would not even want to guess how many descendents he has now.
It is amazing how some families tend to be very prolific (i.e. 10 kids, each having 10+ kids, etc) while others are one or two kids each generation. It really fills up people's DNA with those large families. Devon has this issue with a couple of her lines. Almost all of her matches are from these two lines that had LOTS of kids.
Here is something interesting: I matched a guy at 90 cm with one company and the same guy at 104 with another company.It was a different swab, not an upload of the same test. Is this common ?
0.6% is still a lot of DNA that is being shared. More than likely if you find other cousins that share common surnames with that one, you will be able to start to trace back to where your common ancestor is.
My family is really close, so I know all of my 1st, 2nd, 3rd and 4th cousins, ALL OF THEM, and I was actually able to trace my family tree all the way back to the 900s
I can't comprehend how minuscule the possibility is that you could know 100% of the descendants of all 32 of your great great great grandparents. Wouldn't the families need to be really small in addition to being really close?
They certainly can, although close double cousins (double 1st cousins) are very rare. Once you get out to double 3rd or 4th cousins, you already potentially share a broad enough spectrum of DNA that you look like normal 3rd or 4th cousins.
