Bob, I am also an adoptee born in Brooklyn. The Fifth Avenue Library (with the lion in the front) has all the birth records, if you should choose to go further with your search. My friend found my birth record but the search was extensive.
First, on ancestry I see a slight difference in the month of birth, see:
Robert Kohl, born June 10, 1924 NYC (that includes Kings Co. (Brooklyn).
In 1930 he is living at 304 84 St., Brooklyn.
Robert's wife - Margaret Donnelly 1924-2003 she died in Suffolk Co., on 12-28-2003.
In July 22, 1960 a Robert Kohl is born in Brooklyn - Cert. #30454
In 1993 he was in Centereach, Long Island @ 15 Lehigh Ave, Zip 11720-3606
Bob I just realized a mistake in spelling surname. Let me get back to you.
