Nick - the only thing I can say is that when I left Doriscourt when my baby was 10 days old, her new parents collected her the same day. They have said there was no check on them or anything and they were so worried about this that they went straight to the social services (or whatever it was called over 50 years ago) to report the fact they had this new baby for adoption. It seemed that after a few years of marriage they hadn't been able to produce a baby and they were told, possibly by their GP, about Doriscourt. They applied there to have a baby and they had mine.
I did meet one of the girls who'd had to work there prior to giving birth, some months later. (I would liked to have kept in touch but my mother forbid me, in case anyone found out how we'd met!) By coincidence, although she lived some long way from me, her grandparents lived quite near me. What she did say was that she too, and other girls that had been there the same time as her, just left their babies behind at 10 days, so I assume their new parents just picked them up too. It seems that Mary Walsh was running a private adoption scheme, at least as far as my baby was concerned no money changed hands, but whether this was the norm I don't know.
I know I was told not to mention to anyone when I went to sign the adoption papers that I'd just left the baby, I was to say that I'd decided to let some people my parents knew adopt the baby.
I'm sorry you've not been able to find your birth mother. I used to worry that, because of the nature of the adoption, my daughter's parents were either too old, or something else was wrong that had stopped them going through the normal channels, but as it turned out they were absolutely fine - and as often happens they produced their own child just over a year later. The last time I went to see them (the adoptive parents) the mum said if people ask how many children she has she always says 2, then she looked at me and said "You don't mind me saying that do you, because 1 of them is yours really" Of course I told her I didn't mind and that her daughter was no longer mine. They were adamant from the day they picked up my daughter that when she was an adult they would find me, and when they did her father had photographs of the whole of her lifetime ready for me, which is wonderful.
