| The two CARRICOs above are brothers and have a paper descent
from Charles CARRICO (1770s-1830s), of MD, KY, and Sullivan
Co., IN, through his son, Reason CARRICO (1790s-1878), also
of KY and Sullivan Co., IN. While a paper connection from
Charles to Peter CARRICO I, the 1674 immigrant to Maryland,
has yet to be documented, such a connection has always been
assumed. This connection has been proven through testing
descendants of Charles's sons, Basil and Josiah, both of whom
are a match for the other descendants of Peter CARRICO I.
Unfortunately, the descendants of Reason are not a match with
them. Peter's descendants are Haplogroup
J-2a4b, and these two brothers are Haplogroup R-1b1b-2a1b.
People in different haplogroups cannot have shared a common
ancestor for thousands of years. The inescapable conclusion
is that the two CARRICO brothers have an NPE,
a "non-paternal event" (i.e., a hidden adoption or illicit
paternity), in their patrilineal line. By testing cousins,
the location of this NPE can be determined. |
| We are at least fortunate that the two brothers are well off the modal
haplotype of R1b, particularly in the first 12 markers. And because
they are, they have only one near match in the FTDNA database: with
LITTLETON #89853. Interestingly, this LITTLETON does not remotely
match any of the other 21 LITTLETONs in the LITTLETON
Y-DNA Surname Project. The LITTLETON's lack of matches in the
LITTLETON project may mean that his line is simply a different, less common
LITTLETON line, but it could also mean that he has an NPE in his lineage,
too, so this LITTLETON also needs to test cousins. I have created
a CARRICO
- LITTLETON Node Chart to diagrammatically represent the relationships
here and to guide us on which lines are critical to test. |
CDYa/b is one of a group of markers with multiple counts. Like
most of the multi-copy markers, we do not know the actual order of the
alleles. By convention, they are simply reported lo-hi, as above.
However, their actual order could be any permutation of these values.
In other words, their order could be:
| a |
b |
|
a |
b |
|
a |
b |
|

| GD = 2 |
GD = 1 |
The probability that the same marker would change by a value of one twice
in the same direction in a few generations is extremely low. That
is why a difference of two, when most other markers are the same, is assumed
to have happened in a single mutation event, thus reducing the tabulated
Genetic Difference (GD) between them by one.
This difference might not seem worth mentioning, but our two CARRICOs'
results are not that close for supposedly having only six or eight
generations between them and the LITTLETON because, in such a case, one
would expect the GD at 67 markers to range from 0 to 3. If we count
the difference at CDYa/b as two one-step mutations, they have a GD of 5,
but if we count their difference as one two-step mutation, they have a
GD of 4, giving them a more reasonable GD in light of their presumed relationship. |
