Door of Hope Jersey City NJ

I am looking for my son who was born in Jersey City NJ on 10/16/68. I have finally decided today to start this search after 42 years of thinking about him and wondering how he is, what his life is like, whether he was happy, whether he is alive and whether what I did out of love was the best thing for him. He was 2 1/2 years old when I gave him up for adoption. He was adopted through an adoption service in Long Branch, NJ. Please reply if you have had success in finding your child. I am just beginning my search and can use suggestions. Thank you and God Bless you on your journey.
