Believe it was his uncle

Bob has an interview for the 1969 class blog (Walsh69 if I remember). here is an excerpt from an interview with Bob which indicates Bill Belden was an uncle:

My cousin, Bill Belden, Jr., became president of Belden Brick in 1983. He called and asked me to return to Canton as vice president of marketing, including market and sales analysis. I could not refuse.

As an added note, the Dept of Science had a basketball league in the spring. Our math squad was quite good until March 17th when Ara called Mr Belden back to duty and we reappeared as a bunch of nerds.
