Do You Remember if Jim White, Jr. had a son?

Does anyone remember a ceremony at the Natural Entrance
(around 10+ years ago) amphitheater during which a grandson
of Jim White was honored with a commemorative plaque?

A friend (and former co-employee) remembers something to this
effect, but isn't sure of when or the the full details. I have a partial
memory of such an event, but my details are skimpy at  best.

I realize now that I am not sure if Jim White, Jr. had a second
wife or just just married once. I knew Marguerite White who
was either his only wife or his second wife. Another faint
recollection I  have is that he and Marguerite were married
60+ years so they certainly may have had children, right?

Do you know if Jim Jr.had a son (a grandson to Jim, Sr.)
I will check at the The Family History Center here in town
soon to see what they know?

Thanks.
