    I've been comparing chromosome browser matches between DNA matches, then looking at their family tree's(they have well researched records) and trying to see a potential couple that we'd all share.

    Yes I've learned all too well how many people have the same names , I've spent days researching records to slowly differentiate similar names from each other.

    Also been getting advice from other adoptee genealogists who've used similar methods in order to find their own birth families(they did eventually find their parents using that technique), you work your way down from distant ancestors to the modern day.

    I just dont see that working at all, especially dealing with big nations, its just impossible to do

    It ain't easy that's for sure, a lot of those people I've spoken to have taken almost a decade to finish.

    Nonetheless, if nothing pans out after awhile, then I'll just pay an expert to do it lmao.

    Your Sardinian could be an indication of Italian ancestry then, so it might not even be noise at all

    Okay so I found this explaining why Portugal might come as your closest match and not Iberian, this came from a Cuban since a Cuban was noticing many Cubans coming out with Portugal.

    In response to this
    "a lot of us Cubans are coming up with Portugal. I think it is our Canarian ancestry coming through .. as well as our Galician heritage. ….. in regards to "dots" ... it is essentially the old worthless countries of origin; ."


    he responded with this:

    In regards to “Portugal”, 23&Me has never done the ultra-specific regional testing in Iberia that Living DNA has done in Ireland that allows Living DNA to pinpoint “genetic clusters” localized to certain COUNTIES in Ireland.


    The 23andMe Iberian regional testing is “sorta looks like Portugal”.

    So, why do all Cubans end up getting so many “Portuguese” Dots?

    The answer is in the recent genetic study of the Iberian Peninsula, conducted by the University of Oxford and the Universidad de Santiago de Compostela that is described in this Asturian article below with a link to the actual article after that :

    Patterns of genetic differentiation and the footprints of historical migrations in the Iberian Peninsula:
    https://www.biorxiv.org/content/early/2018/03/12/250191


    The study tested hundreds of individuals in Iberia whose 4 grandparents had lived in the SAME local Iberian region. That provided geographic specificity within Iberia for each individual tested.

    WITHOUT being influenced by political borders or cultural regions, and based SOLELY on the genetic data, the researchers set out do draw a map of “genetic likeness” of Iberia. Here are the results:



    What the study shows is that the modern genetic character of the Iberian Peninsula was shaped by the fact that EACH IBERIAN MEDIEVAL CHRISTIAN KINGDOM “STAYED IN THEIR TRAFFIC LANE (more or less)” AS THE RECONQUISTA PROGRESSED FROM NORTH TO SOUTH.

    Galicia and Western Asturias reconquered, due south, and what is now Portugal became Blue on the Iberian genetic map.

    Eastern Asturias and Cantabria reconquered, due south, to create the Reddish part the Iberian genetic map.

    Old Castilla reconquered, due south, and then veered east, to create the Yellow on the Iberian genetic map.

    Since Asturias was never conquered by the Moors at any time, the Asturians like to tease the rest of Spain by claiming, “España es Asturias y, lo demás, es tierra conquistada” (“Spain is Asturias and, the rest, is conquered land”.

    Genetically, as this University of Oxford/Universidad de Santiago de Compostela study surprisingly shows, that Asturian quip is very real in regards to Portugal:

    Genetically, “Portugal is Galicia and Western Asturias and, the rest, is conquered land”.

    With that knowledge, let’s change the label of “Portugal” to “Galicia and Western Asturias” and see how my KNOWN genealogy back to mid-1700s compares to the University of Oxford/Universidad de Santiago de Compostela map of the Genetics of the Iberian Peninsula:




    Does the approximate percentage of Blue Galicia and Western Asturias Dots now match my Blue Square Galicia and Western Asturias Documented Ancestry back to the 1700s?

    YES, IT DOES.

    The bottom line is that for ANY Latin American individual that is NOT Brazilian, a high number of so-called "Portuguese Dots” does NOT mean Portugal itself. It means Galicia and Western Asturias which represent one of the regions of Spain with the MOST migration to “las Américas”.



    .
    .
    .
    .


    In other words, Latinos who are not Brazilians or even Venezuelans (they have the highest Portuguese population in the Hispanic community) who match with Portugal first will most likely be due to Northwestern Spanish ancestry which they tend to be closer to Portuguese genetically speaking than other Spaniards and this is due to the fact that Galicia and parts of Asturias was part of the Portuguese Kingdom

    Maybe Mexicans can make this exception since it was noted via AncestryDNA geneticists that Mexicans do have Portuguese Jews ancestry but again, I don't know how they differ from other Portuguese, I mean we did have Portuguese settle in colonial Mexico, thousands of them but I am not sure if they were native Portuguese or Jews from Portugal

    But a fact is that colonial Portuguese in the Spanish America were Portuguese Jews and not native Portuguese
