DNA testing is currently available which allows you to trace your
direct paternal or maternal ancestry. Paternal ancestry is traced
through the Y chromosome, which is passed from father to son.
Maternal ancestry is traced through mitochondrial DNA, which is
passed from mother to child (son and daughter). My direct maternal
line goes from me to my mother, Beulah Green, her mother, Alice
Haslam to Alice Southam to Catherine Cameron. The mitochondrial
DNA for Catherine Cameron will match mine, and also her direct
maternal ancestors, such as Margaret Fairgrieve and Margaret
Murdison. At this point, the line has been traced back to Mary
Smith, born in about 1720 in Newlands, Peeblesshire, Scotland, and
her potential mother, Agnes Ramadge.
To find out about the ancient ancestors of these Lowland Scots
women, I requested a mitochondrial DNA test from Ancestry.com
Living on the borders of Scotland, they could have been Celtic,
Pictish, Saxon, Norman, Celtic, Viking or other interesting
ancestries. The test results show that my mitochondrial DNA, as
inherited from Mary Smith, is of haplotype K.This may indicate
ancient Jewish ancestry.
Haplotype K originates in the Middle East, is strong anciently in Northern Italy, Austria and the Alps, and migrated across Europe and into Britain and Scotland. It is strongly represented in Ashkenazi Jews. The most prominent member of this haplotype is Otzi the Iceman, an ancient man whose DNA was discovered and analyzed in the 1990s.
Approximately 32% of people with Ashkenazi Jewish ancestry are in haplogroup K. This high percentage points to a genetic bottleneck occurring some 100 generations ago.Ashkenazi mtDNA K clusters into three subclades seldom found in non-Jews: K1a1b1a, K1a9, and K2a2a. Thus it is possible to detect three individual female ancestors, likely from a Hebrew/Levantine mtDNA pool, whose descendants lived in Europe.
The average of European K frequency is 5.6%. K appears to be highest in the Morbihan (17.5%) and Périgord-Limousin (15.3%) regions of France, and in Norway and Bulgaria (13.3%). The level is 12.5% in Belgium, 11% in Georgia and 10% in Austria and Great Britain.
Haplogroup K was found in the remains of three individuals from the Pre-Pottery Neolithic B site of Tell Ramad, Syria, dating from c. 6000 BC. Haplogroup K has also been found in skeletons of early farmers in Central Europe of around 5500-5300 BC. It has long been known that the techniques of farming, together with associated plant and animal breeds, spread into Europe from the Near East. The evidence from ancient DNA suggests that the Neolithic culture spread by human migration.
Analysis of the mtDNA of Ötzi the Iceman, the frozen mummy from 3300 BC found on the Austrian-Italian border, has shown that Ötzi belongs to the K1 subclade. It cannot be categorized into any of the three modern branches of that subclade (K1a, K1b or K1c). The new subclade has provisionally been named K1ö for Ötzi. Multiplex assay study was able to confirm that the Iceman's mtDNA belongs to a new European mtDNA clade with a very limited distribution amongst modern data sets.
A woman buried some time between 2650 and 2450 BC in a presumed Amorite tomb at Terqa (Tell Ashara), Middle Euphrates Valley, in Syria carried Haplogroup K."
If you are a descendant of Catherine Cameron, or any of her
direct maternal ancestors, then this is your DNA, too.
