67/67 Your
perfect match means you share a common male ancestor with a
person who shares your surname (or variant). Your relatedness
is extremely close with the common ancestor predicted, 50% of
the time, in 3 generations or less and with a 90% probability
within 5 generations. Very few people achieve this close level
of a match. All confidence levels are well within the time
frame that surnames were adopted in Western Europe. |

65-66/67 You
share the same surname (or a variant) with another male and
you mismatch by only one or two 'points' at only one marker.
It's most likely that you matched 36/37 or 37/37 on a previous
Y-DNA test. Very few people achieve this close level of a
match. All confidence levels are well within the time frame
that surnames were adopted in Western Europe. |

63-64/67 You
share the same surname (or a variant) with another male and
you mismatch by only three or four 'points’. It's most likely
that you matched 24/25, 36/37 or 37/37 on previous Y-DNA tests
and your mismatch will be found within the second panel at DYS
#'s 458, 459 a, 459b, 449, or within 464 a-d, or at DYS 576,
570, CDYa or CDYb in our third panel of markers. Your common
ancestor is probably not extremely recent, but your mismatch
is likely within the range of most well established surname
lineages in Western Europe. |

61-62/67 You
share the same surname (or a variant) with another male and
you mismatch by five or six 'points'. Because of the
volatility within some of the markers this is slightly tighter
than being 11/12, 23/25, or 33/37, and it's most likely that
you matched closely on previous Y-DNA tests. It's most likely
that you matched 24/25, 36/37 or 37/37 on previous Y-DNA tests
and your mismatch will be found within the second panel at DYS
#'s 458, 459 a, 459b, 449, or within 464 a-d, or at DYS 576,
570, CDYa or CDYb in our third panel of markers. Your common
ancestor is not very recent, but your mismatch is likely
within the range of most well established surname lineages in
Western Europe. |

60/67 You share
the same surname (or a variant) with another male and you
mismatch by seven 'points'. Because of the volatility within
some of the markers this is about the same as being 11/12 and
it's most likely that you matched 23/25 or 24/25 or 33-34/37
on previous Y-DNA tests. If several or many generations have
passed it is likely that these two lines are related through
other family members. The only way to confirm is to test
additional family lines and find where the mutations took
place. Only by testing additional family members can you find
the person in between each of you...this 'in betweener'
becomes essential for you to find, and without him the
possibility of a match exists, but further evidence must be
pursued. If you test additional individuals you will most
likely find that their DNA falls in-between the persons who
are 7 apart demonstrating relatedness within this family
cluster or haplotype. |

58-59/67 You
share the same surname (or a variant) with another male and
you mismatch by eight or nine ‘points’. It is most likely that
you did not match 24-25/25 or 35-37/37 in previous Y-DNA
tests. If several or many generations have passed it is
possible that you are related through other family members.
The only way to confirm or deny is to test additional family
lines and find where the mutation took place. Only by testing
additional family members can you find the person in between
each of you...this 'in betweener' becomes essential for you to
find, and without him only the possibility of a match exists,
but further evidence should be pursued. If you test additional
individuals you must find the person whose DNA results falls
in-between the persons that are 8 or 9 apart demonstrating
relatedness within this family cluster or haplotype.

56-57/67 is too
far off to be considered related, unless you can find an
“in-betweener’ as for determining ‘Only Possibly Related,’
above. It is important to determine what set of results most
typifies the largest number members of the group you are
'close' to matching. You may be 57/67 with an individual, but
61/67 with the center of the group, and your potential
relatedness to him is through the center of the group.

55/67 You are
not related and the odds greatly favor that you have not
shared a common male ancestor with this person within
thousands of years. |
