girl born 8-30-66 in search of birth family

I was given up for adoption from Family & Child Services. My mother met my father overseas and were apparently pretty serious when an ex contacted him and he moved back to marry her. He never knew my mother was pregnant with me. She came back to the states and told no one that she was pregnant. She was 30 years old when I was born. She had younger twin sister and brother. This is what was given to me in my non-identifying information. Does this sound familiar to anyone? If so please contact me.;)
