We have a shared Ancestor IJK-L15 44,000 BCE from your Haplo group and mine. I also have DYS392 with 11.
A00 is a deeply divergent haplogroup, having split from all other known human lineages about 300,000--200,000 years ago!. This shows that this oldest known lineages lineage of modern human males has been present in west-central Africa for more than 8,000 years, and perhaps much longer!.
However, haplogroup A's oldest sub-clades are exclusively found in Central-Northwest Africa, where it (and by extension the patrilinear ancestor of modern human) is believed to have originated!.
Wild I just saw my last name. Wonder if me and homie are related haha
My surnames go back to Butler, Kavanagh, Neville (King Maker), Plantagent, Boleyn. My brick walls are Smyth's, Burkes, and Youst... Will having my father take another test such as a Y DNA help further my research?
I am also DYS392=11, interesting.
I have a patronymic Welsh surname, but the man who I think is my great-grandfather does not have a father's name recorded on the birth certificate. The surname of my grandfather and the one I've inherited may be from an in family adoption or completely unrelated. I only identified his potential birth through autosomal DNA match of a sister's descendant. On that autosomal I have just one or two very distant related on what I think is the paternal line. They're in other countries, too. With family trees rooted in those countries several generations.
On my other lines I have quite a few fairly close matches and can actually trace ancestry back to before William the Conqueror. However on my male line I have this dead end with my grandfather who died in 43. I would like to know where in the Britain my forebears may be from and what their name actually was. Is Y DNA going to be useful or a waste of money? And which test should I get?
I’ve tested now at 67 markers and waiting on my 111 marker test. At 67 I have 7 matching me but have different surnames.
Until more and more kits come in your 111 reults will likely show anywhere from those same 7 matches all the way down to zero matches. While you are waiting you'll have to drop "down" (up?, lol) to your matches at 37 markers, and concetrate on those that share your surname fro now. I have Whitehead/Whitehand in my tree going back to mid-1700's in NYC. The records switch back and forth between the two surnames referring to the same person, so I treat both as if they are one and the same. fwiw
I realize it's kinda randomly asking but does anyone know a good place to stream new series online ?
@Judah Keith i dunno I would suggest flixportal. Just search on google after it=) -zakai
@Zakai Jalen Thanks, I went there and it seems like a nice service =) I appreciate it!!
@Judah Keith happy to help :)
Please I would like to know how we can determine the Y-haplogroup from the values of 12 markers?
Did your y12 kit not assign you to a haplogroup? Or are you asking how its possible to assign a haplogroup using only 12 markers?

I would like to know If we could predict the Haplogroup only from 12 markers's numbers
@@abswiter1 Yes, but it would be high up in the Big Tree and cover a wide area, and very ancient. Those particular 12 markers were chosed specifically for that purpose if I remember correctly. In my case they can look at those 12, compare them to reference populations, and determine I am predicted to be M-269 for instance. Which covers mostly of Haplogroup R1, perhaps lower on the Big Tree. Another persons, set of 12 might place them in haplogroup J...or I (eye), depending on the values for each of the 12 STRs. If you wish to come firther downstream on the Big Tree, you would need to know the values of even more markers. The more you have, the further down you can predict. So if you had 25, 37, 67, or 111... the more you have values for the further down the Tree you can resonbly predict. Later SNPs can be used to confirm the predictions since it looks at a different kind of mutation.

Thanks for this explicite explanation
Why do my scottish ancestors disappear after the 12 markers
hi, i tested for 37 markers but only get a single match in 12 markers. Questions, is 12 accurate? do I need to upgrade to higher marker?
They need to upgrade to a higher marker
It is a good idea to buy as much as you can afford as an investment. More markers can give finer detail relatively speaking, no pun intended. :) 12 markers are only as accurate as the understanding of the genepool they are being compared against currently is. And 12 are really well understood at this point. Years ago at 37 markers, and because of the large numbers of samples, I was able to place myself in a specific region on a continent, especially those sharing my surname which offered a little more detail. For example, Scotland in the British Isles. At 37 markers would say sit tight unless you wish to make an investment in future discoveries at today's prices. BigY700 or similar being the goal. I saved for the BigY700 for a couple of years and just got my results back. They will tell me much in the coming decade as more BigY700 kits are added to the pool for comparison. \M/
I had a daughter born in 1995 named Alexandra. I was 19. How do I find her? Have scientists ever considered tracing maternal dna in the mitochondrial dna in each cell that are ring shaped? The mitochondria in each cell is the powerhouses of the cell. I read maternal dna is contained in these rings and only 2% of paternal dna leakes through to the child. Could maternal dna in the mitochondrial shuffle and be the source of actual genetic variation if y dna does not recombine and be behind the drifting in pacific rim concept?
Greetings, good luck on your search for your daughter, I truly hope you find her well. To maybe reassure you about the DNA testing as an option in your search, the mitochondra DNA can indeed provide answers through the maternal line as it is the most resilient form of all the DNA, it can provide much information about an individual and can even be found in ancient individuals who have no material left for conventional DNA testing therefore providing information that otherwise would have never been known. The changes and so called " mutations " of the mitochondria only proves the efficiency of the cells ability to adapt through an extreme existence, without changing the original information pertaining to the individual.
just curious if you might know, in the instance of a female person and a mitochondrial test, the second X chromosome should come from the the paternal grandmother, does this actually show up?@@heathermckay5244
