I know William Millring, was friends with his son Bill in high school in Charlotte NC. William Sr has 1 son and 2 daughters.
Please let me know if you would like to chat further.
I would be happy to call you and discuss.

I do think this is the one you are looking for as William Sr is about 75-80, plays piano and they moved from Buffalo about 25 years ago.

Best Regards,
David Wallace
