I am looking for actress names from the ELVIS movie, SPEEDWAY.?

I know that Victoria Meyerlink played Ellie Esterlake, one of the four little girls in the movie. Who played the other three little girls? Please HELP! I like learning who the little kids from the old movies grew up to be.

I tried IMDB, which is how I got Victoria's name.

Nancy Sinatra's role of Susan Jacks first had been offered to the popular 1960s English singer Petula Clark. Ms. Clark turned the part down and it then was given to Sinatra, who also enjoyed popularity as a singer with her #1 songs 'These Boots Were Made For Walking', 'Sugar Town' and 'Something Stupid'.
Victoria Paige Meyerink played precocious Ellie Esterlake. The tiny tot who played Ellie's little sister Annie Esterlake was Patti Jean Keith, the granddaughter of director Norman Taurog. This was one of many films for Mr. Taurog (his eighth one with Elvis), however, this was Patti's only movie role.
Charlotte Stewart played the oft weepy Lori. She then went on to her roles as the much loved teacher Ms. Beadle in the TV series 'Little House on the Prairie' and Betty Briggs in the series 'Twin Peaks'.
