    Lech Valley Bronze Age samples on GEDmatch

    Lech_MBA samples are all poor quality, but here are some of the youngest of Lech_EBA samples.

    All of these are high coverage and dated to 1815-1789 cal BCE (see page 65 in the link below):

    https://science.sciencemag.org/conte...Mittnik-SM.pdf

    GEDmatch kit - sample - closest Eurogenes K15 Single Distance:

    KK8011389 - AITI_43 - in Eurogenes K15: French 5.43
    CP1480384 - AITI_50 - in Eurogenes K15: South_Dutch 6.38
    DG9597754 - AITI_72 - in Eurogenes K15: Spanish_Galicia 7.66
    PS9648941 - AITI_78 - in Eurogenes K15: French 7.47
    KJ6170001 - AITI_120 - in Eurogenes K15: French 5.48
    NJ6500074 - AITI_119 - in Eurogenes K15: French 8.98
    CN5088059 - AITI_2 - in Eurogenes K15: South_Dutch 9.76

    The best coverage of MBA samples has only 35,000 SNPs in K15, while these have ca. 100,000.

    Could it be that these AITI samples were Early Celts or Proto-Celts?

    Wow, AITI_50 is almost identical to me in the K15, my closest is South Dutch at 6.496. I would say yes, Proto-Celts.

    Similarity Map for seven Lech Valley samples dated to 1800-1750 BCE, most similar to France:

    EDIT:

    New Similarity Map, after removing AITI_50 (the most northern-shifted outlier):


    Even more similar to Central French than before, but less similar to Germans:

    Matches center around northern and central France, Switzerland, Tyrol, southern Germany and Belgium/southern Netherlands. Other high matches (70-80%) are found in Britain, Ireland, Spain, Portugal, northern Italy, eastern Austria, then fade in the 60% in the Danube valley and Scandinavia. This geographic distribution strongly suggests a Hallstatt/La Tène connection, so this group of individuals could very well be their ancestors or relatives of ancestors. Furthermore, the Lech Valley, in the Tyrol region of Austria, is exactly within the core of what would later become the Hallstatt culture.

    The article states that 17 of the samples were R1b-P312/S116*, while 10 more appeared to be R1 as well, but not derived beyond L11. Of the other Y-haplogroups identified, there were only one member of haplogroup I and two of G2. I have always maintained that haplogroups I2a2b-L38 and G2a-Z1816 were found among Hallstatt/La Tène Celts, so I wouldn't be surprised if a retesting of these skeletons with better quality DNA yielded these clades.
