Betty Ross
Clarke's first screen role in a "talkie" was as the character Dot Aldrich in "The Age for Love". During the 1930s, she appeared in more than 20 sound films, including both feature films and short films. She typically played character roles, both credited and uncredited. Of note, she replaced the actress Sara Haden as Aunt Millie in two feature length Andy Hardy films. Betty Ross Clarke occasionally was billed in screen credits as Betsy Ross Clarke or Betty Ross Clark, and her name appears as Betty Ross-Clarke in some databases.
