To begin to use autosomal DNA results, we need to understand
the standards that have been offered to us by the experts. We need to be flexible, as this is still a
new science and it changes constantly.
In the very beginning the supposition was that the “larger the segment
shared” the closer the relative. Now it
is becoming apparent that there are exceptions to this “rule”. When we share multiple lines, it is becoming
apparent that we may share larger segments with an individual.
But let us work with the best scenario and leave the
exceptions to when we can prove that they apply. As a general rule, we will find our most
recent relatives with the larger segments.
I like to work with “5”, “3” and “1” for the most distant. For this example I have decided to use “3cm”.
Where do we find out matches?
We must begin with the company that we used for the
testing. I can only talk about 23&me
and Family Finder. The information that
we need to find is the mathematical data.
23&Me: Log in
1.
Family and Friends
2.
List view
3.
Search, enter desired surname
4.
Write down results
5.
My Results
6.
Ancestry Tools
7.
Family Inheritance: Advanced
8.
Compare, enter yourself in the left side
9.
Enter three of your results in the right side
(start with first name)
10.
View in table
You now have the chromosome and segment numbers and enter
these into a spreadsheet
Family
Finder Log In
1.
Family Finder, Matches
2.
Click on Name and enter surname
3.
Under the name there is a small arrow, click on
it
4.
Click on Triangulate
5.
Select In Common With
6.
Write down all these names
7.
Family Finder…Select Chromosome Browser
8.
In the Compare List set to 1+cM
9.
Enter up to five of your names from your list
10.
Select either Download to Excel or view in table
11.
Enter into a spreadsheet
Now that we have our first group of matches, email each one
to see if they will exchange family information. Both programs allow the user to upload a tree
or surname list but this is not always available.
This is an example of what your spreadsheet will look like.

Now you will have to “ find the matches”
Make a color system of 22 colors. I then change the font color for different
segments on the same chromosome.

Lynn has the most matches so I am starting the analysis with
her. She has 6 matches and she descends
from James/Lydia Sizemore, James/Elizabeth Wells
1.
12 Me,
2.
15 Rogers, Fields, Sizemore
3.
17 Rutledge
4.
18 Sizemore
5.
19 Cathy Bennett, Celeste Hogan, Davis
6.
21 Cathy Bennett, Sizemore
I descend from Nathan Blevins brother of James who married
Lydia Sizemore, so that is our most recent shared grandparents
1.
Lynn has more matches to Sizemore than to me but
is one generation more recent. Also,
several of the Sizemore families have Blevins ancestors but so far the
marriages are in the 1750 time period.
Lydia Sizemore George Edward 1750 Annie Hart
The Sizemore sisters descend from William 1798 and Anna Asher (Dillon
Asher/Collett) Clay Co Ky, Dillon is the son of William Asher and Margaret
Blevins
Cathy Bennett descends from
Keziah Sizemore 1829 daughter of John R and Nancy Bowling (James Boling
and Sarah Blevins). She also descends
from Dillon Asher/ Collett
The most recent Sizemore grandparents are Old Ned Sizemore.
The remainder of the group share Blevins ancestry but the most recent shared
grandparent is undetermined at this time.
Rutledge is a descendent of Elisha Walling1707/Mary Blevins and Elisha
Walling Jr and Catherine Blevins and both of these wives need confirmed. The
shared Blevins most recent grandparent has to be from 1720 back due to the known James Blevins grandfather was born 1740 and has to go back
at least one more generation.
These Blevins might connect at any point back to 1720 or this is the
common grandparent.
Celeste Hogan is a descendent of Richard Blevins 1785 and Mary Jones of
Arkansas. This line is on the Old
Settlers Roll. Minimum 65 years gap.
Wash. Co. Court Pleas and Quarterly Sessions,1778-1798 Vol. 1,pg 363.
Ordered to lay off a road from Greasy Cove to the head of Limestone Cove,on the
road to Burke Co.,NC. John Blevins,William Blevins,Jonathan Blevins,Daniel
Blevins,Elisha Blevins,Richard Blevins,also named was William Lewis(my
ancestor),John Hales,Isham Hales,William Hales,James Ward,William Samms,Joseph
Culbertson and others. Could one of these
be the father of Richard 1785
JACaltonDavis descends from Hugh Torbett Blevins 1804 and Anna Looney
of Rhea Tn. His father is very likely David 1776 and Sarah Torbett . Controversy exists surrounding his father but it is accepted
that Hardin same age 1810 Wash Va is a brother.
Next door to each other in that census and then the families migrate to
Rhea Co Tn. Census records support this
location for this family.
Mr Rogers is Anna Foster another Elisha Walling and Mary Blevins
descendent but though son John Allen 1734 and Millicent Jones.
Anna Foster and I match on the same Chromosome#1 segment. Since the first Blevins match for Anna is the
Elisha Walling and Mary Blevins whose children begin about 1732 and my James
was born 1740 he is most likely a nephew and his father would most likely be a
brother to Mary. Elisha Walling, John
and Daniel Blevins are in the 1733 Ann Arundel Tax lists. Clement Redd in his correspondence with Lyman
Draper states that Mary Blevins is the daughter of John Blevins and the sister
of William. I would suggest that my
James is also a brother, supported by the fact that my line stayed close to the
Skaggs and Wallen family and my Nathan first wife was Lydia Skaggs, daughter of
Longhunter Charles Skaggs.
Next week, I will show how to add the spreadsheets of JACalton Davis
and Celeste Hogan to see if we can find
any Chromosome segments that might fill in the gaps back to 1725.
I am very much interested in spreadsheets, but I don't know the first thing about spreadsheets. How will a s/s help me? Is the information produced by a s/s relialable?
ReplyDeleteI have not had time to study your article covering s/s, but intend to do so. I want to thank you for taking the time to show how to do this.
I have been trying for years to find the father of my maternal G G grandfather which was an NPE. About the only thing I have learned via DNA testing is, my great grandfather was the son of a half breed Indian, who was the son of a full blood Indian woman and a white man of either Scottish or Irish decent. Do yo think a s/s will help me to discover the correct surname of my mother's ancestors.
Yes, I do. It is working for me. The data is reliable because you control the sources and what is in it. Are we related? I don't have your name in my project notes but I know that others have shared our site. Do you know what surname your Native American ancestor used? Has either of your parents or their siblings been tested? The more you narrow the field, the easier it is to get results. I will be posting more about Native American soon.
