Help identifying famous? 1940s roller skaters

[aatkin]

I purchased these photos of 1940s roller skaters at an estate sale and would love any info. I believe the couple's names are Jack and Mary. The back of the solo dancer is signed Gloria and the group photo is signed by the "Carnival of Wheels."
