My grandfather was adopted when he was 3 years old and I am trying to do genealogy and I need these records because he did not talk about his birth family at all.I know none of the family names.
More than likely, back in the day when he was adopted, it was a closed adoption. Those records will not be available at all, unless you petition the court with an extraordinary reason why those records are needed - genealogy is not a pressing, life-or-death reason.
