I am using this blog to record my genealogy research progress. My research at this point is concentrated in Tennessee, Virginia, Kentucky and Pennsylvania records. Since many of my ancestors ended up in the Midwest and West my research sometimes takes me in that direction. I also research Irish records.

IBS and Autosomal DNA?
Genealogy and Autosomal DNA may contribute to IBS (Irritable bowel syndrome) but this acronym has another meaning. Identical by state means your sharing a common DNA segment in your autosomal DNA is just a coincidence, and you are not actually related to the person. Too weed out some of these matches and find out whether you are actually related IBD (Identical by descent or you both inherit that segment from a common ancestor) we bring in another acronym SNP (single nucleotide polymorphisms) which are copying errors. If you share at least 500 SNPs, or over, on a segment of shared DNA than you are likely related or IBD.
I went back to my Owens match to check whether we were IBD on the two matching segments. Yes we were. Both were over 500 SNPs
At gedmatch I was able to find cousins who shared a common ancestor at 11 and 12 generations back in Quebec. I noticed the segments I shared with them were IBD, but the segment sizes are generally in the 3cM range. I believe two where in the 5 cM range. This is just one example.

Support for my Hypothesis from autosomal DNA match
The Tenmile Country and Its Pioneer Families: A Genealogical History |
I need to try to unearth something more about these women now in order to possibly solve these brickwalls with the autosomal DNA. Have not been able to find the parents or maiden names in two cases of these women:
- Sarah Campbell born 1812 in possibly Tennessee or North Carolina married Anderson Wray 15 Nov 1832 in Jackson County, Indiana
- Eve Urma born about 1800 in Virginia or Pennsylvania married Jesse Callahan 5 Oct 1814 in Washington County, IN. She may be related to the Urmey family in the same area?
- Francis Unknown born abt. 1785 PA married James D. Owens of Bracken County, Kentucky don't know where or when they marriage took place? Some names which appeared with her in her husbands probate were Aquilla Houke, William Orr, John McMillen, Benjamin Laughlin ( I may have a Houke match?).
- Rachel Unknown b. unknown married to Roger Browning b. 6 Dec 1751 of Greene County, Tennessee
I shared a 25.5 cM block with a Williamson family who lived in Franklin County, Indiana. I am wondering if this match relates to one of these brickwalls? I wonder if several of my matches at FT DNA relate to one of these lines?
Here is my transcription of tax lists for Bracken County, KY. George Owens also named in John Owens will appears with James.

Autosomal DNA What does cM stand for? Plus my current match total
If you share a block in the same location with several matches you likely share a common ancestor. This is true even if the blocks overlap each other. |
The easiest way to understand the FT DNA autosomal results is to start with a definition of cM. It's a genetic measurement and it measures genetic distance. According to Wikipedia "A centimorgan (cM) is a unit that describes a recombination frequency of 1%. In this way we can measure the genetic distance between two loci, based upon their recombination frequency." When you are using the Chromosome browser at FT DNA the higher the cM number you select the larger the segments will be for comparison. 5 cM and over signifies a relationship, and over 10 cM conclusive proof of a relationship. The shared cM numbers on your match pages present a different indicator. The higher the number of shared cM in the match section of your results signifies a higher likelihood of recombination for the shared block. The higher the likelihood of recombination the more likely your match is a close relative. Lower shared cM numbers mean that segment does not recombine as often so your match may be more distant in time. I found this page at FT DNA to be the best explanation of the whole autosomal DNA process http://www.familytreedna.com/faq/answers/default.aspx?faqid=17
So the most important numbers to remember are:
- The longest block. The longer the block the more likely you are to be related.
- Shared cM. The higher this number the more likely your relationship is recent (closer cousin) a lower number could mean your match shares a more distant relationship with you (more distant cousin).
- The Chromo Browser setting number relates to the size of the shared block. The higher the number you set it to the larger segment will be for comparison to one or more matches. You may share many smaller segments of DNA with someone also, so you can set the browser to show segments as low as 1 cM.

Working those Autosomal Results
I received my Autosomal DNA test result last Friday exactly 3 weeks after they received my test kit.

This is my personal knowledge of my ethnicity |
I've uploaded my raw data files from FT DNA to Promethease and Gedmatch. I also got a BGA report from Doug McDonald which gives me a little more insight into my possible ethnic roots.
I have not had much success with Gedmatch so far. This site helps you find possible autosomal match cousins. I initially just uploaded my raw files and got only one match. When I later uploaded a gedcom file I got 503 matches. Most proved to be not significant. Could not find a common ancestor with most. I did find more French Canadian cousins.
I picked up some information about how these DNA percentages tend to correlate with your ancestors. According to The Genetic Genealogist great-grandparents contribute about 12% to your DNA.
What I have learned is you need to use traditional genealogy and family knowledge to put these results into the correct context. I am very pleased with my results so far. The test has been well worth the cost for me.
Here are examples of the reports I received from Doug McDonald:

1940 Census Conclusion
My Final Indexing Numbers |
Finally an index for Chicago was made available for the 1940 Census at Ancestry.com. Found my father and his family immediately. It would have taken me forever going through the 9th ward page by page. They did indeed live in the 9th ward as I thought. They lived in the West Pullman area of Chicago. I did not expect to find them to be that far south. The Kappel family worked for Pullman Rail Car Company for many years. I looked up for a picture of the house the family lived in on Normal Avenue at Google Maps Street View. It appears that this address is a vacant lot. Sadly I could not get a picture of their house. At least I have an idea of what the neighborhood was like. The house was valued $3500 which was $1500 dollars more than the California property belonging to my Forgey grandparents.
I also was able to locate my Grandfather Rudolph Kappel's brothers and their properties. I am not sure whether the John Kappel I found is the correct man? I don't know what his wife's name was? I need to do some more research to see if this is the right guy? The others likely are all correct. Steven was a cabinet maker for the railroad and Joseph was a woodworker at a piano factory. Herman worked in a steel mill like his brother William. My grandfather evidently was unemployed and cleaning alleys for the city.
The information I've found has been very interesting, and hopefully may lead me to cousins who may have family photos? I now have a better idea of the birth order of my Kappel Aunts and Uncles too.
