So why is it that we never hear about this brave lady?
There was another woman, named Colvin, years later who was chosen as a symbol who would end the "back of the bus" practice. Unfortunately, Colvin became pregnant with an older, married man's child. So, her value as a symbol diminished. That was the end of it for her.
Rosa Parks was selected by the NAACP to be a replacement for Colvin. Parks was a creation of political activists. She was manufactured in order to get national publicity to change a bad practice. Parks is well known (and Kirkaldy is not) because Parks was created to be a symbol.
For many of the same reasons you never hear mention of Gen. Robert E. Lee's daughter being arrested in Virginia in 1902 for refusing to give up her seat in the black section of a bus.
