From Evelyn (Grisso) Fawley Pittenger's account of the Grisso family: "Now Dad, so the story goes, wanted to name his new son "Peter", after a Peter Grisso, but Mother held out for "Warren", for the president of the United States, Warren Harding. Dad had his way, though, nevertheless, and Warren became "Pete", a name he carried until his death." (Pete's namesake was the son of Emanuel Gresso, and thus a first cousin to Adam Grisso. He was a schoolteacher, and probably taught Charles in school. His death record lists him as Peter Gresso, but Wabash County school records give his name consistently as Pete Grisso.)

The Social Security death index lists Warren Grisso, b. 25 July 1921, d. June 1979, SSN 311-03-8780 issued in Indiana, last residence Warsaw, IN.
