I am looking for any information on a Morris Gunner. I do not have very much information only the following...

Morris Gunner born on January 24, 1932 in New York (possibly Brooklyn), he was an only child and died in New York on November 16, 2005

his parents are Paul Percy Gunner (born January 27, 1906 and Died October 1982) and Clara Selter

Paul Percy Gunner's parents are Morris and Dora Gunner.
which I received by Paul's SS application. I am unable to read Dora's maiden name but can tell it startes with a "Z" maybe Zwilling????

Any information would be appreciated and thank you in advance....
