Hi Simark, I was also born at Doriscourt, a few years after you. I'm afraid I can't answer your question. As far as I know I was a single birth. However, I've always had a deep rooted feeling I was a twin and grew up constantly asking my mum if I was a twin. May I ask, were you both adopted separately or together? Did Mary Walsh inform your parents you were a twin? I understand if you prefer not to answer these questions. Wishing you all the best with your search for information. Many thanks.
