Abandoned Child Miami Dade County Fl 1955-1962

Do not know any details other than I was abandoned at 3 to 4 years of age. Adoption took place in Miami Fl. Court papers say mother left child on or about 1/12/1961 and gave no information as to child's original name DOBor place of birth. Adopted to couple in Hialeah Fl. Adoption took place on Dec 1 1961. Birth date was assigned by court to be Jan 12, 1959 but then changed again to Jan 12 1958 per doctor's testimony that I was older than thought. Adoption handled by Kimbrell and Braswell.UPDATE DNA has put me in contact with paternal side. Father did time in the navy and lived in Michigan and was divorced (later moved to Ca and remarried) he passed in 2011. He traveled with his band around the Ohio, Michigan and surrounding states on weekends and during the week he delivered dairy products. Father never ever was informed I was conceived. DNA has proven my maternal side has relation to Offenberger's, Schaad's, Ritchies or Ritchey and Tullius surnames. We believe conception was in Ohio or Michigan and mother sent to Fl to give birth.
