DNA Trail...

     I recently got the results of my Geno 2.0 DNA test.  This test gives results for distant ancestors and since I am female, it only gives mitochondrial DNA.  
     I already knew from Thomas' test at FTDNA that the haplogroup for our matrilineal line was J--J2a1a1a2. There is an interesting book written by Bryan Sykes entitled The Seven Daughters of Eve. 
     The "daughters" refer to the 7 haplogroups to which the mitochondrial DNA of Europeans can be traced. Sykes created a story to explain each haplogroup and its migration out of Africa. J or Jasmine as it is referred to, moved out of the Middle East toward Europe about 8,500 years ago, bringing agriculture with it.
     The test makes comparisons between the typical percentages of ethnicities in European populations and the individual (me).  I completed a survey of my known ancestors and their geographical origins.  My largest pool was British.  The typical makeup of that group is 49% Northern European, 33% Mediterranean and 17% Southwest Asian.
      For our line the results were:  43% Northern European; 37% Mediterranean; 18% Southwest Asian and 2% Native American. This last result was a bit of a surprise. 
     I went to a program sponsored by Irish Genealogical Society International and the speaker gave an overview of DNA & genealogy. I ran this result by her, wondering how far back this might be--she said, "think 1700s".  I then found information on the Geno 2.0 website saying that 2% Native American would mean that the DNA was introduced about 5 or 6 generations back.  
     Our matrilineal line is Hogan-->Morehead-->Grandelmyer-->Thompson-->Lewis-->unknown.
     Sarah Jane Lewis was born about 1822 in Tompkins County, New York.  Nothing is known of her mother.  Her father's name was likely John Lewis.  A John Lewis was with her & her family in the 1850 Federal Census in St. Paul, Minnesota Territory. 
     More digging to do!
