may just designate someone who ran an IBM mainframe shop

It's quite possible that he worked for IBM running mainframes on site for the NSA or CIA or any of a myriad of relatively secretive US government agencies.

If so, together with IBM's historic penchant for secrecy, and given that Folden is perhaps closer in age to The Greatest Generation than to The Millenials, he just might not be very visible on Google.

I'd bet that searching "real" databases, e.g. DMV records, Social Security records, IBM employee payroll lists, property tax records, etc, would be far more productive.
