I too was adopted and traced my birth mother, at first she did not want to know, but I sent her a xmas card and then she got in touch.As she lived a long way from me , we never met but exchanged letters , photos and spoke on the phone, this was enough for me , it made things in my life piece together and I was satisfied at that, I have now lost touch again , I think she might have gone into a home perhaps , she would be about 80 ish now.I have also a brother and a sister that I have never met, have tried to trace , but no luck, so yes, give it ago, I wish you good luck with your quest.
