I was reported by 23&me of having Y-haplogroup R-Z92. Additional Big-Y testing from FamilyTreeDNA shows a predicted Y-DNA haplogroup of R-M198.
I have 1 Y-DNA match with 25 markers and 13 matches with 12 markers on FamilyTreeDNA.
To add to what others say, if you're looking for recent relatives, autosomal is the way to go. If you're trying to find out where you came from in history, Y-DNA and mt-DNA will show the way.
R-M198 is an ancient line of Y-DNA. Our paternal line was highly successful at producing male heirs. If it were not so, we would have a younger Y-DNA haplogroup. For our Y-DNA to be R-M198 after many generations is remarkable if the rule of one mutation for every four generations is true.
FWIW - we are all exceptionally good-looking and highly intelligent :):):)
----------
My paternal grandparents immigrated to the USA from the village of Charubin (Podlaski V) in eastern Poland around 1905. I have autosomal cousins from Poland (not a big surprise given that my ancestors were only here in the US two generations before me).
The family name is Harubin (Slater is my step-dad's name) There are a bunch of Harubin descendants in the general area of King of Prussia, Pennsylvania, USA, so there is a non-trivial pool of potential R-M198 relatives, though I don't know how many have taken DNA tests.
Mark Petschek - It's interesting that you mentioned Jewish heritage, because there were 'stories' of our family name, Harubin, sounding vaguely Jewish. The family was Roman Catholic, but for how many generations I don't know. At some points in history, there were strong pushes to convert Jewish people to Catholicism/Orthodox Christianity, under threat of death.
I'm curious as to why you think the haplogroup might be attributed to the Levitical line. If it is, I'll gladly claim to be a descendant of Zadok the priest.
Petri Laasonen - again addressing the Jewish angle, sorry but the term Orthodox can be ambiguous. Was your grandfather an Orthodox Jew, or Eastern/Russian Orthodox (Christian)?
FWIW - The Jewish heritage testing that I've seen only tests for markers for Ashkenazi heritage. To my knowledge, no one has identified any other genetic markers for Jewishness. If that's true, there could be many people from ancient Jewish lines (lost tribes?) that would test as non-Jewish.
From some of the FamilyTreeDNA tests, I do have 0.96% Askenazi DNA.
My autosomal mixture (23&me at the 50% level)
50.3% Polish,
49.5% British/Irish
0.2% Ancient Persian/Caucasian/Mesopotamian.
There is zero autosomal DNA from any of the world's other populations.
My GEDmatch Kit is DY2301564 if anyone cares to compare.
Hope this helps the original poster.
Beyond that...
My mt-DNA Haplogroup is K1b1b, an ancient line of mt-DNA.
My British/Irish ancestors showed up in the USA some time before 1775 and apparently married only other British/Irish people. Yes, there was a fair amount of inbreeding, and the maternal family tree here on Geni has been well documented by many interested family members. I can trace a direct maternal line here in the USA back to 1775. The mother of the female ancestor born in the USA in 1775 is currently unknown.
Despite my maternal line having been here in the USA for 250+ years, I still have plenty of autosomal 4th cousins in several areas of Ireland, and west Yorkshire of England
I believe my maternal line would be considered "Black Irish", possibly indigenous, due to the dark swarthy skin and dark hair common in my maternal line. My maternal line was in Britain/Ireland long before the red-haired, light--skinned Celts showed up, possibly Beaker or older. This maternal line was highly successful at producing female heirs.
--------------------
Because of the above information I assume the Polish and British autosomal portions of my DNA are distinct and separate, ie, I picked up no British/Irish DNA from my paternal line, and I picked up no Polish DNA from my maternal line.
