  • Question about Gedmatch calculator results

    Do these Gedmatch MDLP K23b results corroborate the known history of my Island in the Azores. It is recorded that the primary source of settlers were from the North of Portugal along with Flemings but I have also found historical documents that indicate Sephardic Jews also settled there.

    I have no known Italian ancestors other that one surname that is believed to trace to Venice in the 1400's. I am a little surprised that Italian Bergamo is showing up as my #1 population.

    I'm not entirely sure how to interpret my results from the Jtest.

    The Jtest oracle Results are somewhat different then the one above not sure why. Also It is probably not accurate the calculator is selecting mostly Eastern European populations rather than North Western European populations as a secondary source population.

    These smaller percentages for secondary populations don't seem to corroborate the MDLP K23b results.

    Can someone please enlighten me on how to best interpret the the results from these three calculators.
