Dear Rootschat
My grandmother Mary Elizabeth Amelia Vincent was born 6 Jun 1875. I have asked about her before, so apologies for going over the same ground again.
It was the curious case of her being noted as being born in "South of France" in the 1881 census. (Her brother Robert Richard Vincent was noted as being born in "South America").
I could not find a birth registration record for her. I came to the conclusion that she was adopted. Supporting this conclusion was that her parents (on paper) were Robert John Vincent 7 Jun 1835 and Mary Yorke 8 Jun 1836, who were married on 8 Jan 1861 and that 10 years elapsed before the first birth in 1871. Plus the mother of Robert was Ellen Friend Vincent née Connolly 7 Oct 1799 - 1878 was a "monthly nurse", living at Silver Street (now Beak St.), Westminster. She was exactly the right sort of person to deal with unwanted births. Robert when confronted by the enumerator in the 1881 census said "South of France" knowing that he had no record of a birth. And there the matter rested. With the happy conclusion that my grandmother was the daughter of a wayward young woman unable to deal with the problem.
Until recently:
Then a near relation treated me to a DNA test. My understanding of the process of birth is that the child acquires DNA traits from each of the parents. On Ancestry I have found several "shared matches" and in some cases I have been able to find a common ancestor.
Thinking about the adoption situation:
I concluded that I should get no links (according to the paper records) to the trees of people who were her forebears i.e. the family Vincent and Yorke.
On the other hand (considering the biological parents of Mary Vincent) I should get several links to families who are apparently unrelated to me. Particularly as I am dealing with my grandma - who is only 2 generations away. In looking at these I ought not to find a connection in the paper records.
The problem there is that the failure to find a link will be mixed in with those where lack of diligence also fails to find a link.
My questions; is my thought process correct about the linking of families?
And considering those where there is no apparent link, if I find a female about the right age (born around 1855) in the right area am I likely to identify a specific Mum?
AND then should I make contact with the any descendant of this Mum?
Has anyone been in this sticky situation?
