    Does that still seem odd?

    what do you mean by relatives ?........actual relatives confirmed of number of people 23andme think you are related to ?

    i have 54 for people "related" to me who have 4 + grandparents from Italy ..............of those 6 families are 100% related even though some of their surnames are not Italian now


    I do not bother with any that say 5th cousin as I never have matched any of these


    my numbers below

    Italy (147)

    Has 1+ grandparents (147)
    Has 2+ grandparents (114)
    Has 3+ grandparents (64)
    Has 4+ grandparents (54)

    Question is, with which parent? Let me guess it was phased with your mother? If you don't have your father tested, I guess its just that the phased version doesn't work as well? If your father did an actual test, it would be even more odd. I guess they don't assign segments and relatives with high certainty to a phased version of a parent.

    btw
    one of my sons married a non italian lineage ...........her grandparents are from cornwall england and brittany france



    you got my curiosity up , so I checked my father relatives

    Italy (133)

    Has 1+ grandparents (133)
    Has 2+ grandparents (102)
    Has 3+ grandparents (58)
    Has 4+ grandparents (48)




    BTW,....what is better in your opinion ( or others ) ......DNA shared or segments shared ? ...................

    It gets more odd than that. Like I said.
    If I go to relatives on fathers side I only have 43 out of 1500!
    But if I go to reset and add In settings only to include Relatives on fathers side with at least 1 Italian born grandparent I have only 7 DNA relatives out of those 43 ?
    And out of the 43 DNA relatives some are fairly close 3rd cousins some more distant 4th cousins one is 5th to 6th distant cousin.

    I roughly get these percentages and segments shared with 100% known relatives

    father ..48% DNA shared .....26 segments
    son ...48% DNA shared .......22 segments
    1st cousin .... 14% DNA shared .......33 segments
    2nd cousin ...10% DNA shared .....26 segments
    3rd cousin.... 2% DNA shared ........3 segments
    3rd cousin ...once removed ...1% DNA shared ....2 segments
    4th cousin...half % shared ......2 segments

    I have no closer DNA relatives than 3rd cousins on fathers side.
    I think the lack of DNA relatives might be a combination of No one in the Area where my father is from testing with 23andMe combined with these village Town communities in the area my father is from being a bit inbred lol.

    That's quite low for 3rd cousins and very high for a 2nd one? My proven second cousin shares 130 cM, 7 segments with more than 7 cM, plus a handful smaller ones, which are of course not reliable. A lot depends on the size of a segment, a safer bet is only more than 10 if there are more than one of that size, or larger than 20 if its a single one. And that's the very lowest treshold, usually it should be more.

    1st cousin is my maternal side ...............all others are my paternal side ..................do you think this makes a difference? ie, maternal from paternal


    BTW....after 1st cousin on my maternal....next best maternal side is 4th cousin ....half % DNA shared and 2 segments
