Title: Unexpected parentage (NPE ) could it be sperm.donation
Post by: brigidmac on Thursday 31 August 23 09:23 BST (UK)
We are now coming up to the era where people  descended from test tube babies could come up as DNA matches

Has anyone else had experience of this?.
My mother matched the child of an American sperm doner

  this procedure has existed in UK since 1958

 I Wonder if there was an age limit for men taking part . ?

& How many mother's thought their children would never learn about this .modern day DNA results could leave their children thinking that they were the result of an affair

Hard to believe that Louise Brown is now 45, seems like only yesterday when her birth hit the headlines all over the world.

Also begs the question of what a child is told if his “Dad” and birth Mother who both raises him or her as their own child when the birth Mother was actually a surrogate for another Woman’s egg and the sperm used to fertilise the egg is not from the man the child knows as Dad?

I agree

It would also throw a spanner in DNA match results if a different woman's eggs were used .
There were a few media cases where mistakes had been found or legal issues raised

Anyone trying to trace their royal lines back

Should be cautious about possible infidelity along their lines

But who would have thought artificial insemination  would date back to HENRY IV

If the following is true

Poor old Danny Dyer may have to get his royal line DNA tested.  ;)

You do not always know who the mother is either, in cases such as the recorded mother was the grandmother and the mother was the baby's "much older sister", to cover up an illegitimate birth. I am sure that is the case for my 3xgreat gran Clara whose recorded mother was 51 at the time, yet Clara had a much older sisters first name as a middle name.

It's been going on a lot, I've heard.

In some cases it's exposed so called 'Fertility Fraud' where the doctor performing the fertility procedure has been found to have fraudulently been the donor.

I am reminded of a story in William Shatner's "Weird or What?" TV series: A woman was prosecuted for fraudulently claiming child support payments as the children's DNA didn't match hers. This surprised her, as she'd been there when they were born. Her lawyer unearthed a similar case where it was explained that the mother was originally going to be a twin, but the eggs coalesced resulting in different DNA depending where in her body the samples came from. Further tests led to a "not guilty" verdict.

Hello Chris

I think this that you refer to, is called Chimerism, where a child does not acquire all the usual DNA of their parents.

See the Lydia Fairchild Benefit Claim / Court Case in the United States.

I've always said to ones who think DNA is a quick solution in ancestry, that I still need all the available paperwork myself  :)

I can no longer find the person who had 'sperm doner" on their tree .they matched my mother thru a different branch but I was curious enough at the time to message the manager of that tree about the circumstances
He told me his brother or uncle  had been a sperm donor in the 1970s which resulted in lots of matches to himself from a younger generation.


Thanks for the shock . horror stories 😲

Also cases of the sperm donor not bringing up their child.

Bridal pregnancies was very, very common, often to test paternity/trial marriage etc, but we have to allow some cases where the father was another man. For instance if a man gallantly stepped forward for a pregnant woman where the father had fled or died, or the real father decided to marry another woman. If such a man did that, and helped a woman out in a sticky situation, then it makes him very much an ancestor, and he was one of those responsible for your existence.

Such as, for example, in rural Suffolk, Mary Bloggs got pregnant in January 1784, the father was a Joe Soap. In March 1784, Joe found Mary was expecting a baby, so he ran away to London to escape his duty. Mary then met local man James Hamilton (born 1750) and he stepped forward and married Mary in August 1784. Mary had a baby boy called James Hamilton in October 1784. Any descendants of James Hamilton Jnr born Oct 1784 will have Joe Soap as a blood ancestor, but James Hamilton Snr (born 1750) was the father in every way but blood, so should be considered an ancestor of James Hamiton Jnr's descendants.

The "Wierd or What?" episode I mentioned is showing NOW, on Blaze, Freeview Channel 64. There are 3 items in each episode; the chimera one should be in the next half hour. May be findable on blaze.tv also.
