Any children from them ?

There are 3 minor children mentioned on that Clarence's 1962 Death notice. It does not mention whether they were from his first or second marriage.
His estate file starts here: https://www.familysearch.org/ark:/61903/3:1:3Q9M-CSS1-NX41?i=1756

==> These estate files tend to mention all of a deceased's children, so maybe this is NOT your guy?
