Johnny Whipple Brick at the Utah Shakespearean Festival

Yesterday we saw Noel Coward's 1930 play entitled Private Lives at the Utah Shakespearean Festival in Cedar City. As we left the Randall L. Jones Theatre following the performance, I spied this brick in the pavement:
I also noticed the bio and photo of another Whipple--Jennifer--in a this year's commemorative book. (Was that Jennifer Whipple who identified herself as "Jennifer" in the green show before the evening performance of Shakespeare's Comedy of Errors?)

I haven't yet managed to identify any of the Whipples there. Maybe they are related to the Whipples in nearby Las Vegas?

(P.S. Both Private Lives and Comedy of Errors were fantastic!
