Circus High Diver

I am looking for Earl and Judith Walker of Ann Arbor. I understand from family folk lore Judith ran away from MN with Earl when he was a circus/carnival performer. Judith (Danielson) was born in 1903 in Sweden and died in Ann Arbor in 1975. They were married(??)and toured the country until they settled in MI. His father was supposed to be a professor at the University at Ann Arbor. Earl's stage name was Jack Kelly. Sorry for the sketchy info. I also have a picture of Judith in front of a circus wagon in Galesberg, Illinois in 1925. The name on the wagon cannot be read except for "Stadium". Many thanks for any info
