Found out recently from my sister to whom I am close, that when I went looking again only for med history as told only child all along. She happened to walk into my full sisters home and found my full brother there and they had letter from agency. 10 children, 8 fathers. About me who they didnt know of either. They were saying well she doesnt know about us, so we can just pretend we never got it. It was my sister who was shall we say angry and grabbed the letter, said she is a sister, and went and made the phone call that set all moving. If she hadnt walked in there then, and been the sister she is, I would never have known anything. She is the only one I have contact from and we are close. Rest dont seem to connect at all it seems.
