My father was adopted in 1955 or 1956. His birth name was Billy Wayne Sharp. I am here looking for his siblings. His mother name was Lula Mae Sharp and the father might have been Robert (unsure). His birth date is 05/21/1951. All children were remove by the State of Texas and ordered by the judge to be seperated. The adoption took place in Gainsville or Greenville. Any help would be appreciated.
