Girl born 2-4-66 Jacksonville Fl. adopted in NY

I was born in Jacksonville Florida on February 4, 1966. I was adopted at 1109 Carroll Place. At a Term of the Family Court of the State of New York, County of Bronx. The adoption was finalized October 10, 1966, by the Hon. Phillip B. Thurston. Docket No. A-834/66. The Attorneys involved were, Joseph Black of Black & Collyer in Florida and Joseph Spencer in NY The adoption papers, given to me by my adopted parents, say my natural mothers name is/was Donna L. Barker. I was also given a letter from the Jacksonville Florida lawyer's office [Black & Collyer], to my adoptive parents, dated January 11, 1966 says; BABY DUE JANUARY 23, 1966: NATURAL MOTHER-- is 19 years old, 5'2" tall, 130 lbs, has light brown hair, blue eyes, was never married, has one brother, is of Irish-English racial extraction with some Indian, was a high school graduate, was employed by Southern Bell Telephone Company, is Protestant and had a normal medical history. NATURAL FATHER--Is 26years old is 5' 11" tall' weighs 180 lbs, has black hair, brown eyes, is of Anglo-American racial extraction, is in construction work, is nice looking (according to natural mother), is from Jacksonville FL and West Virginia, he is married but separated from his wife (again this was all in 1965/1966) My adopted parents were in the hospital when I was born. They took me back to NY 2 or3 days later. My adopted parents were in the hospital when I was born. They gave their information to the nurse in the hospital, so their names are on what I believe to be my original birth certificate. They took me back to NY 2 or3 days later. I cant register in NY States adoption registry because I was born in Florida. Florida says they think the adoption is illegal because there is no amended birth certificate. They say the one I have is the original. I donҒt understand how this could be. If the names of my adopted parents were on my original birth certificate why would they have to adopt me at all? Im so confused! My e-mail is JULIE667@aol.com
