This is confusing.
Point one:
I feel sure MY names were chosen by my adoptive parents.
For the sake of argument, pretend my name is
Harriet Ann So and So.
My Birth Mother also has a daughter, born after me, that SHE named Harriet. And her other daughter, born just after me as well, is called Sarah Harriet. See what I mean. So she has not only used my name once, but twice.
What I wondered about when I found out my birth mother had another child whom she named "Harriet" was whether they'd told her what my adoptive family had named me.
On the one hand - why do that? Would just be torturing yourself, no.
But what a WEIRD co-incidence if not?
And I can't see how the children wouldn't think soemthing was up with it too, like she'd never gotten over me or something and had to name the rest of her kids after me. (Barring the son - she had more imagination there. To some extent anyway! Her son has the same name as her husband and brother.)
Point two:
I have never sent a letter. The Catholic Charities who organised the adoption sent a bunch of letters out saying: We're tyring to contact So and So, please get in touch if it's you. No response.
So - I don't know if she's received anything.
