Mitochondrial DNA and finding a cousin

Serendipity has struck and we have found a cousin.... It helps that due to some time-lags, they are the same generation as my late grandmother (who was born 1905), though considerably younger. Thus there are fewer generations to leap back to the MRCA (most recent common ancestor). This is not important genetically, but just simply in terms of getting the story across. The mutual forebear is Hannah Doxey (b. 1750), entirely in the female line, and thanks to three coincidences, this was also the name of our cousin's grandmother, so not such an alien name as it might have been. In fact, not alien at all!

There are three reasons how this serendiptous naming has happened:
Reason 1) Hannah's daughter married back into the Doxey name, having married a first cousin.
Reason 2) Our cousin was illegitimate, and thus brought up by grandparents, which brings the older folk to the fore, baby Hannah being given the name of her grandmother's mother.
Reason 3) The aforementioned time lags which reduce the number of generations we need to get from 1750 to now.

We look forward to the testing results in due course, and to learning more about Hannah Doxey and her family. (She was evicted from her childhood home, Wirksworth, Derbyshire, in 1786, and this resulted in three deaths in the family that year. We will contend that the eldest daughter then 12, eloped, ran away, five years later. Which DNA will prove.)

Grandfather's grandfather's grandmother

It occurred to me, that there should be dozens of these in the family tree, but of course adding them up there's just eight. I have three, partly as there is a cousin marriage which consumes the fourth; and then as on the paternal side we can't quite go back that far. Two of the three are Welsh, and two are called Margaret: Rebecca Phillips b. 1780, Margaret Evans b. 1792 (a twin), Margaret Trewhella b. 1784.

Paternal grandmothers' paternal grandmothers are interesting if you look at x-dna. This gets passed on - intact? via son to paternal granddaughter. I need to do some more reading around this.

The one thing I won't comment on too much is y-dna as this doesn't seem very interesting to me at all... Apologies!

Coefficient of grandparents

I'll start by saying this is not really a coefficient, which implies multiplying and producing a figure between 0 and 1, but rather, involves adding. Much easier.

My grandparents have the figure of 88. Why? Because they died when I was respectively 2, 12, 34 and 40, which adds up to 88. In other words I had 88 years' worth of grandparents, while I was alive.

An interesting contrast is the figure for my great aunt Hilda (name slightly changed). Her figure is extremely low, in fact possibly as low as the figure can ever be. It is MINUS 80. Her grandparents died 2, 15, 28 and 35 years before she was born. This came about for two reasons: firstly that she was the youngest grandchild born when both parents were well on in their forties (and both parents had lots of older siblings as well); secondly the grandparents (who would all have been at least in their eighties) were from a different generation and all suffered some form of childhood loss, or in one case extreme poverty.

When I think of my meeting with aunt Hilda (born 1916), I cannot believe her grandparents belonged to such an early epoch, for instance
* her grandmother was orphaned in 1844 (and the wrong side of the Pennines to boot)
* her grandmother features in the will of Lancelot Gibson (b. 1785), who flourished as estate manager in northern Northumberland in another era
* her grandfather, a bit of a charmer, was the cause of Joseph Carline re-writing his will in 1856 (although this will never went to probate)
* her grandmother died only a hundred years after her great-great-great-grandfather, John Brasier, who kept rabbits at Checkhill Common, Kinver passed away in the 1790s
* when her grandmother was orphaned, in 1844, and brought back across the Pennines, her Scottish great-grandmother was then still living (but where was she from?)
* when her eldest grandparent was born, George IV was still on the throne (whose great-uncle was tutored by Edmond Halley that 'invented' Halley's Comet)
* her grandfather was the result of the marriage of the children of two brothers from a hat-making family in Derbyshire, born in the 1780s. One, careful, organised and wealthy. The other, disorganised, dissolute and poor.
* her grandmother, whose illegitimate birth has caused me much consternation, allegedly sat in 'that chair over there'

I would be interested to hear if her record of 'coefficient of grandparents' can easily be matched.
