    YSEQ’s response on regards to my Y18959 order, they deemed it not stable:

    ‘Unfortunately your wished SNP is located in a region which has a very high homology to a fragment on chromosome 1. Due to the high frequency of recombination events which can occur this SNP is not stable.
    Therefore we do not recommend to analyze this SNP’

    This is true, there is a theoretical probability of such recombination. However, the random selection of 176 samples from R1b Basal Subclades project shows that all positive samples (10 of 176) belong to the single Y18959 branch. Such results would be not possible in a case of the significant real recombination in this region. So, the practical results are not in an agreement with the YSEQ assumption.

    So all samples under BY611 and Y5587 that have done NGS tests are consistent? Even yfull seems to have rated it high. Unfortunately YSEQ is not adding it so therefore not able to test it as an individual SNP.

    DCBarry, do you mind sharing the source of this information? Is it a collective family memory or did someone find some data on this? I know that in Italy they have demographic and tax registers archived in the capital of each province or at the medieval capital of the local political entity.

    There are a few locations in Puglia that were settled by Albanians of Skanderbeg with the permission of Ferdinand of Naples. They were of the orthodox faith (like Arvanites) and one of their settlements was Casalvecchio, which is very close to Volturara. If you happen to know anyone from there, maybe it would be possible to verify this connection it real.
