THANKS TO ALL
Yes, Robert Moses was Secretary of State from 1927 - 1929.
I now can reference the Robert Moses whose signature is on one of my digital
slides of a document here, as "the same" man as the Parkway & bridges man
;-)
Thanks again for all the responses.  I have several new reference links
bookmarked now.
