Does anyone know Maurice R Nicholas, or the Nicholas family?

Hello folks. This might be a weird ask, but does anyone know Maurice R Nicholas, or his daughters, sharon & michelle?

I work at an antique shop and I think we have a huge bunch of their mail and a number of photos from the 50s as well. Was just curious as to why they were ever donated, since he appears to still be alive. He'd be around 93 today, I think.

I don't own the items so they're not mine to sell, that one is up to my boss. But if anyone knows the family & could put me in touch I'd be more than happy to send them digital scans of their old photos & mail.
