My great-great-great Grandfather Johann/John Kaser was from Zurich and his wife Anna Muster was from Oberflachs in the Aargua canton- not too far from your Kasers.They spoke German and we actually have a male relative in this line named "Bern Kaser!"So who knows!My cousin Dana Kaser-Nicolini,(another granddaughter of Louis Conrad Kaser) has posted our mutual Kaser family line on this forum. I think the most likely explanation for the R2 result of my male Kaser family member is that a Sinti or Jenisch child was adopted into a Kaser family.He was probably unaware of his gypsy origins. In fact, until as recently as the 1970's, Switzerland had a government condoned program that forcibly removed Sinti children from their "unfit" gypsy parents and gave them up for adoption to "proper" well-off, German families. This policy was called "Children of the Road" and in fact a film by Urs Egger, CHILDREN OF THE ROAD, has been made about this unfortunate fact in Swiss history.One of the other explanations seems implausible: a male from India or Sri Lanka or a Sinti male had a romance or marriage with a Swiss woman! Highly dubious given the differences in language, culture, and ethnicity.I think I mentioned in a prior posting that over 90% of R2s are on the Indian sub-continent, EXCEPT for the German Gypsies- the Sinti.Over half the Sinti males are R2.Only about 2% of the Rom or Romanian Gypsies are R2. So it seems the Sinti are genetically different although they are considered a sub-group of the Rom based on language similarities. I have read that the Jenisch of Switzerland (a Sinti and German mix)are not accepted by the Swiss because they're not German/white enough OR the Rom because they are not Gypsy enough/too white! Anyway, it is unlikely that my Kasers would have been advertising their Sinti/Jenisch heritage even if they were aware of it; the Sinti and Jenisch have long been discriminated against and many were sent to Nazi death camps. We tend to romanticize Gypsies for their beautiful music, dancing and their freedom loving lifestyle, but the reality is that they have had a hell of a time and still face bias and racism to this day! I will be interested to see if any other Kasers come up with any R2 results in the future.Not sure if you have your Haplogroup type or have posted it anywhere. Let me know!I saw Owen's results.
