This is the last of a series of posts on my deep maternal ancestors, identified through analysis of mitochondrial DNA (mtDNA) which is passed only from the mother to the child and so provides a trail of maternal ancestors identifiable through the mutations accumulated in the mtDNA. In this post I summarize the “recent” maternal ancestors who lived through the beginnings of agriculture in Britain, the British bronze age, the British iron age, the Roman occupation, and post-Roman Britain.
In my previous post on my deep maternal ancestors (https://mountainsrivers.com/2014/02/16/deep-maternal-ancestors-out-of-africa-into-ice-age-europe/) I summarized the “grandmothers” who contributed specific mutations to my mtDNA that allow me to trace them (and approximately when and where they lived) all the way back to Mitochondrial Eve, the most recent common maternal ancestor of all living humans. These women were real and specific individuals, and Sykes and others have given the older ones specific names (usually starting with the letter of the haplogroup they founded). I have followed this by giving names to the founders of the subgroups to which I belong. In this post, I give a brief biography of each of these ancestral grandmothers, starting with Mitochondrial Eve, placing them in evolutionary, geographic, and climatic context. Continue reading →
I have only been able to trace my maternal ancestors back to my great-great-grandmother, Amelia Buckmaster, who was born in 1809 in Hounslow, Middlesex, England and who died in 1892 in Wallingford, Berkshire, England. I recently had my mitochondrial DNA tested (see an earlier post for more on mtDNA) and the results indicated that my mtDNA haplogroup is U. I did some research on the specific mutations identified in my mtDNA and identified my subgroup more specifically as U5a1a1.This means that I now know quite a lot about specific maternal ancestors and where and when they lived, all the way back to Mitochondrial Eve who lived in Africa 192,400 years ago.
Mitochondrial Eve is the name given to the matrilineal most recent common ancestor (MRCA) of modern humans. In other words, she was the woman from whom all living humans today descend, on their mother’s side, and through the mothers of those mothers and so on, back until all lines converge on one person. Mitochondrial Eve is estimated to have lived around 192,400 years ago ago in southern Africa(which makes her approximately my great*9,650th grandmother). Continue reading →
I have had an interest in the history of my family since childhood, when I wrote a short history of the Mathers family that drew heavily on documents and recollections of family members, particularly those of a great-uncle and great-aunt born in Scotland in the 19th century. When I discovered Tolkien’s Lord of the Rings trilogy as a teenager, I was fascinated by the genealogical charts in the Appendices to the Lord of the Rings. For some reason, I find the tracing of connections to a larger history deeply satisfying. Over the last ten years, I returned to researching my ancestry using the powerful tools offered by the Internet, with access to databases and historical records that I would not have dreamed possible before.
